Rereading your post I think you looked at the back parcel shelf for the ID plate holes. The two holes are in front of the passenger seat at the left hand end of the rolled front to the shelf, the one covered in black vinyl. The vinyl may have been replaced by a previous owner as the holes looked a bit grotty so feel behind the lip of the shelf for evidence of two holes about 2" apart. The brass ID plate was screwed here so the car ID number was visible when using the two way radio. For early Minis the ID number was the last digit of the year followed by the three numerics on the car's registration plate. So a 1967 Cooper S with registration plate EVJ602 would be car ID 7602.

Bearing in mind that an absence of things like the badge holes, hole in the roof, etc doesnt mean it wasnt an SPO41 car as many didnt make it to the police but were sold off to the public as was with my car, although it went to an employee at the factory. The same guy I bought it off.

Forgot to add, the ex bathurst car was Police pack as well and it never made it to the Police. Probably a good thing too as those cars were probably flogged by the cops. Mine was only driven on Sundays.

Ben,

If you PM me your internet email address I will send you some documents to help develop your knowledge of SPO41 and enable you to confirm aspects of your car.

SPO16 Lowered Frame Seats - about 1 1/2" was removed from the seat frame tubing and the two cut ends welded together. You'll see the circular weld just below the seat back strengthening fillet in the following photo. Normal seats are continuous tubing.

Image

The correct specification 1 1/2" SU's and modified inlet manifold appear on the second-hand market from time to time. I bought a complete set on eBay a few weeks ago. Be aware that the Australian Police Cooper S configuration was specifically designed by SU for the purpose (as opposed to just using a setup from an MGB, for instance) and was given its own specification number, which is AUD488. You should look for this marking on the float bowl tags - AUD488L and AUD488R. Basically they were HS4 bodies with vacuum take-off (for the CCV breather setup) and Cooper S 1 1/4" float bowls with 30 degree adapters. The intake manifold is a modified version of the standard AEG573 with the studs relocated to take the different configuration of the HS4's and the ports opened up. The remaining unused stud holes which penetrate the chamber are blocked off by Aralditing a socket head grub screw in the hole. A modified version of the MG Midget one-piece heat shield was used in lieu of the two-piece Cooper S item and a pair of thinner spacers were used in place of the thicker Cooper S ones.

Image

The handbrake warning light was activated by a fabricated switch mechanism utilising a standard Linread door switch (see photo below). There's usually an additional small hole down low at the front of the handbrake bracket where this is bolted. It uses one of the existing bolts as well. Check that area on yours. The wire (blue with purple trace) ran under the carpet and up to the light and provided earth switching. A plain green wire ran from the light to the voltage stabiliser providing power.

Image

The tacho was a Smiths Impulse RVI-1003/00 mounted in front of the driver on the standard Smiths flat bracket screwed under the rail that runs under the windscreen.

Ah yes, you are correct. I do in fact have these two holes through the vinyl on the left side. Roughly two inch spacing, lower parcel shelf rail.

NSW Police used different types of Wibroc external mirrors. The main one was as you see fitted to the wrecked S on the trailer. It slid over the leading edge of the drivers door and had two grub screws that may have left a mark along the seam where the outer door panel folds over the inner above the top hinge. They also used the Sportsmans mirror (Bullet shaped racing mirror). Your holes look like the latter has been fitted.
I'll post some photos later.


I don't have any holes for Wibroc mirrors. Here are photos of the holes in the doors, plus the mirrors that were on the car when I got it. There is obviously an extra hole. On the passenger side, that extra hole is from a "grub" screw, i.e. not drilled/stripped like on the driver's side. Am I correct that a "grub screw" is what we'd call a sheet metal screw--sharp point, coarse thread, used to just make a hole and grab metal at the same time, no nut for the back?

Mine is RVC1006-00F, dated 10/99; obviously not original. But the upper mounting holes are there.

In exactly the location in your picture, there is either a small spot weld or the end of a sheared off screw. I'm betting on the latter. Will look underneath the car another day for the pointy part (quite pointy in parts!). I do not find the blue/purple wire nor the green one, but there are four green ones to the voltage regulator if that means anything.

Definitely have this cut/weld on both front seats on my car.

Thanks again Doug!

So here's another question (don't laugh too loudly)...

Is there any way to research the history of my car? I.e., can I write to a government agency in Australia that would be able to tell me the license plate number, owners, police ownership period, etc.? Or is this information dust at this point?

Anyone have a set of proper 1 1/2" SUs they could part with? Minis are extremely rare in the US, much less Cooper S ex-police minis from Australia... :) If you ask a local parts house for something for a mini, they say, "Is that 2005 or 2006?" Most people here don't even know the original mini even existed.

How hard is it to find police bits, i.e. aerial, siren, skid plates, sun visor, driving lights, tacho? If I could find my license plate number, I could fabricate a brass i.d. plate (anyone have a photo?).

Thanks all,
bmc

In theory there are three organisations who would've had these records - the manufacturer (BLMCA), the registration authority (NSW RTA) and the original owner (NSW Police). I can assure you that none of these organisations have the information you are after. BMC and BLMCA records from the 1960's and 70's were discarded in the various takeovers by Jaguar-Rover etc. I did a Freedom of Information request on the NSW Road Traffic Authority for my cars and had a phone call from a guy in the records section (who was ex-BMC Australia so sympathetic to my cause) but RTA shredded all the vehicle registration records from the 1970's in 1980. NSW Police also do not have the records from back then, unfortunately.

The only other source of this information is original paperwork that came with the car, such as the driver's handbook.

I'll talk to you via email on this.

Al the bits you mention are very hard to acquire but not impossible. I'll email you some intelligence.

:) LOL, I've been asking myself that very same question for a long time now. Well, about Oz S at first, now ex-cop Oz S...and especially given that I am a relative newbie in minis, I have to say that I got very, very lucky.

As my dad always said, "I'd rather be lucky than good." 8)

All I know is that the guy I bought it from was in Maryland (eastern USA) and he claimed he had gone over to Oz and bought both my car and the one that Mark (mmalleck) is restoring here in Seattle also. I bought both from Peter in September of 2008 or so, when I first showed up on this forum.

Don't know if this is truly how they came to be in the states, but that's his story in any case.

I do have a few questions for now.

Carbs--I have the set on the car, and another rebuilt set. The rebuilt ones are non-cooper, but wonder what they're from. On the car are numbers AUC870 and AUC871, with tags that have AUD146L and AUD146R on them. The rebuilt ones have AUD146L and R, but are numbered AUC8450 and AUC1342. They also have vacuum takeoffs which I don't think should be there. Any thoughts on what the numbers tell me about these four carbs?




They're not the original carbs, and they are made up of bitza carbs from other applications. The carb tags are I believe correct for a pair of MK2 S 1.25 carbs, so don't lose them at any cost. Its just the carb bodies which are not the correct casting numbers. The 1342 would normally be paired with a 1341 on a sprite I believe, and AUC8450 is a standard 1100 mini/moke carburetor. The vacuum takeoffs for vac advance dizzies (not fitted to Cooper S obviously) are usually fitted to the twin carb closest to the clutch. That is why the 1341 has a vac take off, as well as the standard 1100 carb.

If you take off the dash pots, you will notice that the pistons may differ from right to left. The two pistons you may find are in the image below. The piston on your right is a twin SU piston, with two breather ports. The piston on the left is a standard SU piston with no ports. Both carb inlet throats should have a cut out for a port on the front face of the carb body on both sides. A standard throat has it on one side only.

Thanks Mick. Any thoughts on the pair on the car now, AUC870 and AUC871?

They will be the correct pair of carbs to use on the MK2 manifold.

You can make a complete set using a combination of what you have there at least.

Just pulled the dash pots, and you're correct. The 8450 is like the left one in the photo, the 1342 is like the right one. Does this difference change performance of the carbs when they are used together as a pair? You may recall that they were quite nicely rebuilt, and my reason for purchasing them was to get the mk2 airbox attached to them. I'd like to sell them again at some point (I'm rebuilding my own set, i.e. the 870/871 and/or looking for 1.5s), but I don't feel it's right to advertise them as Cooper S carbs when they're not. I wonder if they are effectively the same thing or not?

Ben

I think the 870/871 already are a complete set, yes? They are what I received on the car. I just plan to resell the rebuilt ones sans airbox, and keep mine.

With the exception of the pistons, they are functionally the same. The differing pistons will have an effect in transition, how much I could not tell you. I would expect the extra ports on the twin damper pistons perhaps improve response times to changes in load. I can't see an unmatched pair being a good thing, one piston will operate differently to the other in an identical situation. How much of a difference it makes in actual operation I would only be guessing.
