I just found this thread, which is great because it is so recent. I am working on my 73 Challenger's interior and I am realizing that, while my doors were treated with anti-rust coating inside while I had it in restoration, the window regulators and tracks are incredibly dirty. Also, the passenger side window is hitting the door frame near the mirror as it comes up. It seems to be tilting too far to the right; not sure why. I sprayed some white lithium grease into the tracks but it is not helping with this. I have the body service manual and some diagrams I downloaded, but I have removed the window hardware on my previous Challenger and it was no fun - and I never had the chance to replace it before I sold that car for parts. Has anyone posted on adjusting the windows? I actually need to pull the glass (or lock it in the up position as you all did here) and pull out the regulator for cleaning, but it would be good to get a feel for making the adjustments. Looking at the bottom of the door, it looks like the front track is bolted down all the way to the outside (or right). Thanks for any suggestions. Kansan, I hope your windows are working well now.
