Just about to start a resto on the rear / quarter windows on my 66sd. The 2 back windows would not go down even half way. Now that I have the driver side back window and regulator removed I can see that all the wheels are seized or in a fixed position. When I  rebuilt the regulators etc on my 57 I was able to purchase a refit wheel kit from danchuk. Is there such a kit available for a 66 beaumont? I am assuming it would be the same as a 66 chevelle. Has anyone done this refit? I will clean up all the channels are grease them but I need to know where I can get a rear window mechanism/ regulator wheel kit.  I do not as of yet have a 66 chevelle catalogue. Any tips on this project much appreciated. Thanks
