So I'm sitting here in Africa, and had plenty of time to read this entire thread. All caught up.
Not surprised about the windshield rust, luckily that is an easy/cheap fix on that area. My first red '69 project had the same issue. The hidden stuff beneath the paint seems awfully familiar, oh yeah my car was like that. Hahaha
I was kidding with my body guy a couple weeks ago, after having gone through this same thing as you are. I should have just bought a Dynacorn body to begin with. Doh!
Looking forward to the updates. If that were my car, I'd keep it white. Very few clean bright white (not Dover white) Camaros out there.
