Floor pans

[Dizzi141]

I'm not quite sure where to put this but here seems about the right place...

My baby has just come out of her MOT having had some welding done but I have a feeling she has had her last patch on this floor pan. So, I'm going to replace the flor pan. I have a man who can weld, he's going to show me whilst replacing my floor pans. But how easy is it to replace the floor? I will probably be buying 2 half floors. How much should be cut out?

Thanks! Lorna

What to cut out depends on what's there and what's not!

If the sills have been repaired with the wide panels that overlap the floor a lot, then leave that in place if it is solid and overlap the new floor with it, just make sure the inner step still makes a solid connection with the inner sill / floor. On botched cars, they tend to leave a layer of rotted floor in between the inner step and the 'wide' sill/floor piece - This gives a pretty strengthles repair but the MOT man won't see holes so it tends to get passed off.

If the floor is rotten right up to the sill and the bottom of the inner step has holes, you can get floor pans that have the inner step repair piece already attached - using those, you just cut the inner step at the 90 degree bend and weld the new one along where the bend was. then you need to make sure the floorpan / inner step is well connected with the sill.

However, this work is structural, so firstly it's best to make sure the sill itself (including the inner boxing plate) is good. There's not much point welding new floor to dodgy sills..... this'll just create more work in the long run.
