I'm just about to replace the floorpans in my hydro 67 deluxe and was told by a mini shop that he didn't have any that suited hydro.
Is that a crock of sh!t? the reason i ask is that the covers for the lines etc are the same from a dry or wet car.

Anyone shed some light for me?

umm a dry car doesnt have covers for hydro lines!?

Floor pans are the same, the hydro is just routed along them. Only real differences are subframes and cross member on the firewall. as for those covers, i suppose dry cars had them for brake lines but they just screw onto it so no worries and ull want some of them just in case.

Later hydro cars (67? on) had trays in the floor for hydro lines etc. These trays stayed until Mini production ceased- 1978, even though all cars after `73? were dry suspension.
Earlier ones had flat floors with the pipes clipped on- with a little tin protective cover each end. We've got one of those (now dry suspension).

Crossmember on the firewall is the same for all Oz Minis, but hydros had 4 bolts in top, dry cars had 4 studs. No, I dunno why either!

Floor pan pressing for OZ built Minis from 67 is unique to OZ. UK built cars don't have the full length protective cover. (Or any other protective cover for that matter????)
Available replacement floor panel sections would most likely be to the UK pattern.
Best bet for floor pan repairs is to find a good OZ floor pan and cut the section out that you need.
If you need the mounting holes for the protective covers you can probably modify the UK panels. Don't know if the grooves in the floor pressing match between OZ and UK panels.

Nav,
I have just replaced a floorpan in 73 mini, with hydro, I couldn't find a replacement one with the hydro line channel in it. Apparently they are all UK panels and as was said they didn't have the hydro. You can get a pre rodchange or a post rodchange panel but i don't know the difference between them. When you weld the new one in the hydro and brake lines will just sit against the floor, and there is a gap between the cover and the floor. As miniron has said best idea is to find a donor car and cut the floor out of that. I have one more car to do so i will be going for that option.
Steve.

Thanks for the reply guys.

I have talked to a mate who is replacing floor pans in his k so i'll look at his when he gets his floor pans

following the train of thought here, i have just picked up a Mini convertible which has had its floor reinforcement done on the UNDERside of the floor pan rather than on the INSIDE of the floor pan which (given limited google research) seems to be the way that they do it these days to ensure the structural rigidity. There is limited rust on the floorpan where some twat hasnt put the roof on when its been raining..!!!

so i am now looking at cutting out the floor and replacing it with a new one, then inserting all of the correct ADR approved reinforcement on the inside of the car.

Is replacing an entire floor pan with new produced panels a viable (intelligent) option? I was considering the whole donor option, but didnt want to be cutting up another Mini for no reason, plus i need to ensure that the floor is as perfect as it can be because its going to be what holds this thing together....

Last question.. the car also has hydro.... if you get a floor pan without hydro covers, can you just weld somethign over the top to protect them, or is there more to it than that.

From what I've read I think you'd be best to replace with new floor pans. They're not too expensive I believe... Not sure about the hydro line covers though.

replacing the whole floor in your convertible is a really good plan - I'd seriously consider converting it to dry suspension so you don't have the hassle of routing the lines, OR you can route the steel hydro lines differently, up in the exhaust tunnel, rather than straight under the floor - a mate of mine has an S where the hydro pipes are in the tunnel instead of under floor plates - very well protected up there, and for you there's no worry with new panels

I never would have thought of routong the lines up the middle like that.
Thats a great idea.

Does anyone know if it is possible to get the whole floor pan? mine is completely cactus

The replacement pans I have seen seem to be thinner & more flimsy.

I'd be going for a donar floor in that convertible. But like you say, chances are if a mini has a good floor is it probably a good mini and a shame to wreck. Oh wait, unless it has been driven by willy or Aussie

Original Oz floors (my 1964 850) were 1.6mm thick, the UK front pans I bought were 1.0mm thick. But they didn't fit too bad with a bit of cutting and shutting in the corners.

I replaced the entire floor in my mini, using those replacement panels. One problem I came across is that the front panel ends at the front of the crossmember and the back panel starts at the back of the crossmember, which leaves the area under the crossmember. I ended up buying another rear panel to cut up and use to cover this area. Changed over from Hydro to dry, to eliminate the chanelling of the hydro lines.

These reproduction panels as Zizzle said, are thinner and pretty flimsy.

Why is it that the original panels are 1.6mm thick, but someone makes a reproduction panel thats nearly half as thin...!! DOesnt make sense... From my perspective, the floor doesnt need to be super strong because of the amount of reinforcement that will be going in... i just need to make sure the start is not rusty.

Now that i have forked out for a hydro pump from Minispares, i kinda wanna keep the hydro. This set has no leaks or anything either, so its perfect..!!!
