Hey Fellas, I'm working on my 76 2 door.. this car seems to have had many things changed out through out the years.. My window was getting hard to roll up or down.. I took the door panel off and found the regulator dry, the very little grease it has is dry and crusty.. I also found that one of the channel rollers is seized or at least very,hard to roll.. but looking up the replacement rollers the pictures show that the "roller" is more of a square slider.. (D6AZ-5323240-A).. I also see that there are replacement complete regulators available but for 70-73 and not 74 and on.. although the pictures I have seen of the replacement regulator looks a lot like the one I took out of the car.. What have you guys done for the round rollers? and do I even have the right regulator in my 76? it does have the inner door handle at the bottom
