Dude!! I've been 4 hours and can't get the glass back in after the regulator install. I know this post is old, but if you could help at all, that'd be great!!Just got done replacing the rear quarter glass and rollers on my 67 Dart this weekend. Not hard but is time consuming and took me 10 miniutes or so just to figure out how to install the spring retainer clips since its kind of a blind install.
