I am not a expert on 32 parts, but I think I have both of the rear door regulators. I will send you a pic if you can identify them. Please E-mail me at cty40899@centurytel.net for the pics.
Just for your information A passenger rear door opener machanism will work for front driver side. rear window regulators won't . Front ones have a (6) bolt mounting and two (2) lift arms. 4dr sedan rears have (4) mounting screws and only one(1) lift arm similar to the 32-34 pickups. Repop 34 window mechanisms will work they are (6) bolt mountings but 32's have 6 raised mounting pads (about1/2 inch) . You can use flat washers to space the 33-34's out. no one will ever see the washers as they are behind the mechanism.
