Hey guys, you've been great giving me tons of knowledge with my 70 SS rust bucket and I am hoping you can give me some guidance on this one. I am cutting out all the pans from cowl to rear bumper in 3 pieces and want to know if there is a correct sequence to go in. My son and I have removed almost all of the trunk pan and have found the cross brace at the rear seat / trunk welded to the inner rear wheelhouses. My one piece trunk has a brace at this intersection of trunk to seat. I think I must remove the old one, CORRECT? Then the rear seat sheetmetal looks like it goes in next on top of the rear brace / trunk pan and then the floorpan from rear seat to cowl / firewall. Does this sound right? Is there any possibility that removing them in the wrong sequence will rack my body? The body mounts are solid under the passeger part of the body but nothing left in the trunk area. One more thing, where is the VIN stamped in the frame? I looked along the driver side by the rear wheel and cannot find it. Thanks for all your help.

I would not remove both at the same time without some bracing. On my 69, the floor goes on top of the rear seat brace, then the trunk pan on top, then the rear seat backing on top of that. Don't know about the 70.

Andy, I tok off the rear seat backing, 1st top, then the trunk pan is 2nd down, then the brace from wheelhouse to wheelhouse 3rd down, then the rear seat pan last on the bottom of all layers of sheetmetal. I was going to leave the interior pans intact and do the trunk 1st.

I would do it that way.

Just between you and me, if you get a couple of the layers switched around, probably no one will know but you :)
