Rob,
Looking good, great progress, you should have it done in time for the BCA Nationals. I can't wait to see it. And you will love driving it!
Regarding the convertible top and rear window, I'm not sure how a glass window would fold down into the well. Would it have a folding seem in the middle of the glass? I went with the original vinyl. It's been 12 years now and it still looks like new. Of course it rarely sees sunlight and I've only put the top down a couple of times. With proper care, a vinyl rear window on a pampered car should last for years. BTW, how long has the top been folded in a box. I had one in a box for years waiting to be installed. My convertible top installer, said that it would be difficult to get the "box memory" wrinkles out. So he ordered a brand new one just to make sure it was tight and wrinkle free. Just my two cents.
Keep the updates and photos coming.
