I have the window tracks from the passemger door of my '74 Challenger. I replaced the door with one from a '71, which is different.
Also included is a bunch of rollers, guides, etc. for both early and late style window tracks. These parts are both used and new, since I rebuilt my mismatched set and had to buy two full kits.
How does $50 plus freight for the whole mess sound? If you only are interested in some of the parts, make me an offer.
