Need Help with Vinyl Roof Disease on '72 Scamp

Did the swiss cheese car have a roof in as bad a shape? Let me splain why everyone says to flush a car with a roof like this one.

I am sure you know how a roof is put together on one of these. Maybe you aren't thinking about it, so let me remind you. First, there's the inner roof skin. Then there are many reinforcing braces spot welded to that. Finally, the outer roof skin. That's a three layer sammich. I bet that roof has rust between the braces and outer skin, the braces and the inner skin, all the way down the sail panels, into the trunk (he's just not found it yet), into the rear quarters, all the way down the A pillars, and even into the cowl area and into the front fenders. That car is hiding a LOT more rust than meets the eye. I ga-roan-tee.

Inner roof skin?

Uh, no. There is no inner roof skin.

The roof skin on an A body is one layer thick. It’s spot welded in about 200 spots, 50 or so spots per edge. Across the front windshield channel, in the drip rail area on both sides, and across the rear window. It sounds like a lot, but it’s a couple hours with a spot weld cutter.

The only places where there are multiple layers is where the roof skin overlays the pillars, window channels, and hard top structure. And it’s really just the thin flange where the skin is spot welded on. But the parts that are rusted out in the pictures are all the single layer roof skin. Same rust damage as on my bronze Dart GT. Most of that rust can be taken care of with the roof skin replacement. You do need a donor for the roof skin though, they aren’t reproduced.

Pascamp has it right too, you don’t need full quarters. Someone will have those upper quarter/lower C pillar panels. The Dutchman you can buy if you can’t find it.

That’s not a parts car. My bronze GT has a very similar rust damage pattern. Roof skin because of the stupid vinyl top (worst idea ever), some small areas of the upper quarter because of the vinyl coverage there, and the spare tire well. And nothing else. I got a parts car and removed the roof skin, it’s not a big deal at all. Just spot welds to put it back on.
