66 cuda window glass question

If you're not in too big a hurry you can get it from Gary Goers-
http://www.garygoers.net/home.php

He also has some fairly obscure early-A stuff so it's worth it to get his catalog which is not online to my knowledge.

He's pretty much mail order only. What you want is 1/32" glass setting tape # ES15132 ($0.25 per foot).

I did all my 65 Valiant glass with this stuff & it worked perfectly.
