while replacing the sills on my clubman estate i noticed there's actually 2 panels (the floor panel and the sill panel) with a small gap between them where the front legs would bolt in (in the rear bins). i had planed to bolt it through the floors with a plate underneath to spread the loads, but with the gap between the panels i'm wondering if this will make the panels warp. i dont really care if the inside bends, but i dont want the sills to look caved in... did anybody experience this or is the gap negligeable and i should just bolt it in and forget about it?

There shouldn't be a gap betwen the sills, but if there is, then there is!
With roll gages, their inherent srength means that any fitting issues will end up with distorted panels. I fitted new outer sills to my rally Cooper 's' quite recently and when I bolted the front part of the cage back in it slightly distorted the sill. I guess it doesn't really matter as the strength is there and, after all, that's why you put a cage in to begin with.
A 3 mm spreader plate of, say, 4" x 3" on the outside, welded on, as the MSA regulations require, will help somewhat.

Does the car have oversills fitted as they may account for the gap,especially if they have been badly fitted.
