One of the differences between a Mini K and a MK2 S is the length of the front guard to body join cover strip.
On the S the strip is shorter as the original type narrow guard flares had a very narrow slot width where the body join is.
The full length body join strip wouldn't fit in the narrow width slot of the flare so it was shortened by about an inch or so???
Can anybody confirm this.

This is one of the tell tales I use but i have never measured it. Visually the seam cover starts a bit higher to clear the flares.



Cars without flares will have full length seam covers.

Your car is the third I have come across without flares. Car 1545 and 2036 were the others. I am not sure if there was a delete option available for certain states or overseas orders.

I had a MK2 S 5/1970 build with the short cover strip.

Looking at the engine pic it doesn't have the S bolt in the front head stud position.
Instead it has the standard type stud as per the non S 1275 blocks.
The non S 1275 block is cast differently to the S block in the area around the water pump.
The S block is a little weaker in this area hence the bolt and only 25lb/ft torque
On the S block the bolt hole goes into the water jacket area behind the water pump and has a thread insert to reduce the thread from IIRC, 3/8" to 5/16".
On the non S block the stud hole doesn't carry through into the water jacket area behind the water pump.

I couldn't understand which part of the picture.
I'm sorry, could you mark bolt in the photo?

"Instead it has the standard type stud as per the non S 1275 blocks."

Non S blocks didn't have a stud or a bolt. (except maybe late GT Clubman?)

The stud with washer and nut on your engine is this one. On a Cooper S engine a bolt is used in place of the stud.

Is it possible that someone cracked the bolt by overtightening and then replaced with a stud? I've seen that happen.

I agree. That is the bit I don't understand.
I thought non-S blocks did not have the bolt near the thermostat or the extra 3/8" stud near the heater take-off. In the photos, this car has both extra bolt/or studs. The original 5/16" bolts seem to have been NLA for some time, although ARP now offer them.

Stop trying to confuse the poor girl. The engine is a Cooper S, you can see the side cover breather can. The engine number is also a big clue (I don't mean the actual numbers, I'm talking about the cut off rivets that are only on imported motors.)
What is the point of talking about seam cover lengths and flare supports when the whole front has clearly been changed?

We need to see the numbers and stop arguing about irrelevant details, next thing it will be hose clamps.

I have managed to get my hands on a couple of new 11th head bolts if required.

Morris 1100 I'll send you some rivets to cut off if you like.

long time no see.
I got a lot of comments, but I'm sorry I'm late to see it.

My mini hasn't come back from the painting factory yet.
I want to check the chassis number quickly.

When I talked to my former owner, he said, "It's definitely the body of the Australian Cooper S."


Now I want to find a genuine Cooper S rocker cover and an air cleaner box.

Is it possible to buy them from Australia?

Which web site should I visit?

How do you find old parts when you find them?

For example an auction? Is it a MINI specialty store?

Hi, This looks like original Cooper S rocker cover:
