I am working on my 1963 New Yorker and i need 2 window lift motors for the rear doors. Is there a Dorman lift motor that will work? i tried the Dorman 742-300 and it does not fit at all. The motor on the one door has a number on it 1964028. If i can find a replacement for that motor i would go that route. but i find not thing on the internet. Any Help?
