'73 Rear Window install
Thought I'd post some pics in case someone was considering/needing a rear window install. I removed the window to have the car painted and while it was out I had it tinted.
Bought this kit from Zip, they are the only ones I found that provided the butyl primer with the kit. The primer creates a really strong bond, so make sure you mark the center of the glass and the center of the body on the inside prior to putting on the butyl or primer. Once the the butyl comes into contact with primer it's not going to move left or right.
Then I followed these instructions: http://www.corvettemagazine.com/body...ip-repair.html
Masked off the body and window.
Finished product:
As you can see, there is gap between the body and glass due to the butyl, but that's how they came from the factory. If you have questions I'd be glad to help.
If you don't want the gap, Chevrolet put out a Service Bulletin, which recommended using caulking instead of butyl. You can access the Service Bulletin via Tom73's website: http://www.73spot.com/bulletin_files/rwindow.pdf

Thanks for posting this. I am planning on putting in a new back window when I redo part of my interior project this summer. The glass that is in it is heavily scratched from when the previous owner had the car repainted. It looks like the orbital sander was used on the edges of the glass area and scratched it pretty bad.

It's in the instruction link above.
"Using a sharp awl or scribe, put a hole into the adhesive weatherstrip between the body and the backglass. Look for a place where the awl will go through easily. You do not want to be twisting or turning the awl because if you catch the corner of the glass, you could break it. Just push the awl straight in and through."
"Now feed the adhesive cutting wire [included in the set from Zip, it's the wire in the bag] through the hole. Let it extend about 8" on either side of the glass. Wrap about 3" of wire around a broken stir stick or screwdriver to make a T-handle. Now with a sawing motion, pull the wire around the glass, sawing and cutting the adhesive as you go. This can be done by one person, but it is much easier with another pair of hands, one pair on the inside and another pair on the outside. When cutting the adhesive, do not pull out away from the glass but try to stay parallel with it. This will keep the wire from hitting the painted surface next to the glass."
