David,Thanks for the pics and link. That is kinda how I want to do the a pillar. I think the b pillar attaches to roof braces with spot welds mostly so I will be using my spot weld cutter alot. The c pillars are one of my concerns. On my 66 malibu at the top of quarter panel up on sail panel it overlapped the roof panel with spot welds and was filled with lead. Melted the lead out and cut out spot welds to replace quarter. So on that one and most cars, not sure about newer cars, there is a factory overlap. I guess in 80 they still done that?? Don't think I have enough c pillar on replacement to do that with. May just "peel" off skin at rear where it runs over into back window upper channel and plug weld that part back in. Thoughts?? I do really appreciate all the tips. Thanks guys
Look at pages 15 and 16 of Donovan's thread on his Cutlass. The roof skin overlaps the quarters and looks to include some of the upper frame for the rear window. Back there, I would take it apart the way the factory put it together using the spot weld cutter and put it back together the same way. I hope this helps....
