Top replacement?

That‘s what I was thinking. Not sure if the cowl comes off of the plenum by drilling the spot welds above the firewall, or if I have to take the whole thing, plenum and all off. I ordered a body assembly manual from ebay that is supposed to show how it all fits together. I’m going to study that and try to come up with a game plan. It’s just disappointing to have to go a little further after all the work I’ve done already. I already have the body braced with steel angle across the door openings and crossed braced between them. I guess I could rig up some cross bracing from the inner B-pillar panes and across the inner roof supports to keep it all square. I made jigs up keep the spring hangars square and correct when I replaced part of one of the sub-frames, and cross-braced the entire trunk surround from my donor car when I removed it. It all came out square and true, but it was a lot of work. I don’t want to end up with a windshield that doesn’t fit, or side windows that won’t seal. For my rear window I made a plywood jig before I took it apart and then fitted the donor trunk surround/lower window frame to that. It came out pretty close.
