okay - so after a weekend (and some good, some not so good welding practice) I've got my rear cross member installed (Thanks Clive!).

everything turned out pretty good. The chassis wasn't as rotten as I thought it might have been and tail ends that I had cut off weren't too bad. That said the cross member was toast. some parts I didn't even have to cut! it was a long two days over the weekend but its done. Thanks to everyone who in the past had posted pictures/etc - they were all a really big help.

Not AFC710010 but the other longer ones. Can you get these separate or do you need them with the floor? Both are rotten but I was thinking of something a little more sturdy than the thin ali (maybe checker) and thought I could build my own but the runners are rotten.
