Shifting gears to deal with the quarter glass and the top frame. After some review and discussion on another thread, I decided to test out a few proposals that would allow me to retain the Cougar door and quarter glass.
With the Cougar glass installed, there are fitment issues to the 67/68 Mustang top. This is a well known issue and arises from the curvature of the Mustang glass line near the rear of the door glass and the back curve of the quarter glass. The Mustang door glass is actually not flat across the top. The Cougar door glass is essentially flat and this line continues for 3" or so on the quarter glass.
So when combined, the Cougar quarter glass will not move up enough. It is ~ 1/2" low and the back edge is perfectly tight against the flange on the top frame and there is not space for the weatherstrip.
There were suggestions to tilt/shim the top frame and a maybe it would fit. No go.
1/2" shim and tilted back. This opens up the lowermost corner but still leaves the upper corner in contact. It also causes a “arch” in the intermediate sections of the frame above the door glass.
3/4" shim with tilt.Still no help.
Lets cut the flange off and reposition it. A few spot welds and slice right along the 90-degree corner.
Proper quarter glass placement w/o the flange.
The next frame section still needs some work but repositioned flange tacked in place.
1/2" gap everywhere for the weatherstrip.
Total time about 2 hours and one piece of 15 gauge 2"x16".
I like it. Mi piace molto.
