The previous owner looks to have patched up the floor (with galv sheet) area above the rhs sills and seamed them onto the sill instead of spot welding it. This is making replacing the sill a nightmare! I've tried searching for spot welds but there are only a few visible. I've tried careful use of an air chisel, but to tell the truth, judging by the chewed up and heavily patched state of the floor, I would like to replace the whole cargo floor area with new metal. It will make replacing the sills and rear crossmember much easier.
Has anyone on the forum had any experience of the cargo floors that the vw suppliers can provide? I know they are of varying quality, and the cost of carriage up to these parts is not insignificant. I have half a mind to get some profile sheet from a local metal fabricators and make up my own.
