Targa C3??
You can buy aftermarket one piece panels. They don't fit particularly well, but they exist...
I'm not sure what the attraction is to make it a targa intead of T-Top, though. It will be unique, but not in a good way, value-wise, and the only difference functionally would be no bar when the tops are off. Not much of a difference for what you'd have to go through in my opinion.

Point being; I think without proper reinforcements, there is going to be a lot of structural flex. That's not to say it can't be done though.

The only problems would be finishing the areas that were cut to make it look stock. You could get an astro top instead of modifying the t tops.

If you're using a vendor other than Astro, I apologize and am curious as to who it is.
What I can say is that the *external* fit pictured in the first thread looks better than what I've got on my car, but mine seal.
I can search for the photo I did if you want to seee it.

Most of the people in the first thread seemed to like it. The second thread is for the t top replacement. Never used those.
I have the one piece and I get no leaks and it fits just as good as the t tops.
palmbeachvette76: likes it, doesn't seal well, is a win "for the price difference"
qwank: fitment issues, but is dealing with it because it's a good deal. Huge gap in the front of hte window. doesn't seal well.
682xlr8: liked it a lot, "sealing is a joke", "be careful when washing the car"
7t9l82: not a bad product, as the others have described
texasbaehr: uniformly positive review
superbuickguy: poor communication (well, GM doesn't like to talk much about the glass tops either
), 1) terrible customer service and terrible delivery
2) poor manufacturing tolerances
3) poor quality control
rosslato: uniformly positive review
So 2 positive reviews and a lot of "good for the price", assuming you can deal with sealing issues.
I already have a pair of glass tops that seal well, so clearly I'm not their target market. I am vaguely interested in the acrylic tops though. It'd be nice to have something lighter to put on the car.
So perhaps my original comment is too harsh, but I definitely think this is an instance of buyer beware - or at least be prepared.
