I think Golden Leaf Automotive might have them

I checked the GM parts book and the interchange book. Any 1965-1966 Pontiac or Chevy with 2 doors will have the regulator you need, regardless of whether it's a 2 dr ht, sedan or convertible. That should really help with your search.

Hi... I managed to find a vent regulator, NOS on line. So that's out of the way. The window regulator was the biggest problem. The GM parts book, 7609589 says this is the correct #. The interchange, Hollander, says 7609589, is the correct number.
OER reproduces that part number, but they say it fits everything BUT a 2 dr sedan. Trying to get an answer from OEM was an exercise in futility. The sales department people just know what's written on the spec sheet. Most of the tech people are the same, they have never worked on a 2 dr sedan.
So I'm going to order the OER product after talking to Chev/Pont people who have the "hands on " experience. Along with the replies here, the general consensus is that 7609589 is the correct part and will work.

I will get back to you when it arrives and let you know.
