Torredcuda,
This worked for me ONCE! Do you know anyone who works for a car dealer, preferably, one that was a past Mopar dealer?
I had a friend that use to work at the local Dodge/Chrysler/Plymouth dealership (Jim Glaze in Redlands CA, no longer in business), and I was in need of a rear window for a 67 notch back. I was having your kind of luck with my search. After talking to him about my dilemma, he looked up the parts number and then checked the computer for dealers who might have one in their inventory. Me of little faith, thought no way anyone would still have a piece of glass for a 30-year-old vehicle. But, low and behold one was found, at a dealership in Spokane Washington “Spokane Chrysler”.
I called up there and talked to the parts department manager and he agreed to send it, I had to pay extra for the packing, da##ed curved glass, but even with that and shipping I only had to pay a little over $500, which I turned over happily, to get my prized jewel.
It work once, it may work again, especially for a quarter window.
Good luck in your search, and I will keep my eyes open as well
