Hi everybody from a german Gas Junkie

Dear all, my car is a Plymouth Sport Fury 1966 2-door Hardtop and i happy to be in this forum. I'm trying to repair the rear right window regulator mechanism. What I'm missing are parts. Specifically, I need either a complete lifting mechanism or, ideally, just the guide rollers that run in the rails. Can these be ordered anywhere in the USA? I had already looked at Rockauto. Maybe one of you has ideas or an address where something like this is available?

THX!!
