71 roadrunner 1/4 window install.. any trick?

Im going to be putting in my 1/4 windows in my 71 roadrunner and was wondering if theres much a trick for it? I had a heckuva time taking them out and putting them in the way I took them out, I would certainly scratch up the paint. any help is appreciated.

Take the long metal track that the window rides on out and mount the window on it first. Then you can slide the whole thing back in the opening. They are tricky so make sure you tape up all painted areas around the openoing to prevent chips/scratches. I just did mine on a 71 RR and I followed what the chassis manuel stated, worked great...Good Luck

I guess I never thought to looked in the manual.. haha. thanks!
