build stage
 

can i weld in the tranny tunnel etc before doing the rear end? Would this cause me any problems?

What do you mean by the rear end? If its the diff cage, and rear supports, thats going to be ok. If its the bit behind the seats, I'd wait until you have something to square it up against.

I did the transmission tunnel before doing the rear suspension and diff area and had no problems.

Cheers Ginge

i did the same.

cheers everyone, makes that job easier.
