my driver side window will not roll up all the way and it is kind of **** eyed. it will not sit flush up against the back wing window like the passenger window will. i took the paneling off to take a look. there appears to be some adjusting bolts but i have no clue if thats true or not and how to adjust my window so it will not leak water when it rains. any help would be awsome. thanks, kevin

 

The best thing to do is buy a 1966 mustang shop manual. You can still get reproductions of them and they answer all your questions. Shop manuals of today suck, but back then they were detailed.[sm=smiley20.gif]

 

Sound's like an adjustment. If it turns out to be the regulator, aftermarket replacements are available from places like Mustangs Unlimited, etc.
