Does anyone have any tips for re-installing the rear quarter windows (1971 vintage)? I have to put one back in that decided to fall out of the track after one of the plastic guide wheels broke. Any help would be appreciated! Thanks.

Fischer body manual gives you step by step. Takes some patience (what doesn't!) to get adjusted. Use other side for reference if you have to. If there was a spring behind the front roller, make sure to use it or it will wobble badly.
