Red Five Eight very very cool factory assembly pic. I wonder if thats my sub? Tim I think it would be worth the effort now that I have the floor out ( albeit in pieces) for me to remove the upper side metal edge and try to put the new floor back in as one piece. If it wont go with one side off I'll just go ahead and remove the edge on the other side. Then put the new floor in and reweld the side angles. One of the angles on mine needs some repair any way. I have found with that big chunk of plywood out the rear body becomes very wiggly. After the body comes back from the blaster I will prime and paint the underside and the new floor will go in right away so as to keep the body as rigid as possible. Thanks everyone for all the replies. Didn't think I would see so many. Must be a lot of panels and burbs lurking out there.
