Power windows issue

Hi folks,
Considering my old 1974 Fury Gran Sedan (4 door hardtop), here is my last trouble. Yesterday, the driver side window broke down again. Not electrical, it's (again) a mechanical failure. The pinions broke again, the window gets down, but does not lift up without hand help. I've already replaced the pinions once, this is such a pain in the a.. to replace them, awfull.:BangHead:
So my question is. I'm looking for a modern electric system swap. I've seen many of them for FLAT windows...
