Due to an an obstruction in the tailgate (create by some work I did), the tailgate window got hung up, and is now crooked. The obstruction is cleared, but now the window goes up and down fine, but when all the way closed the passenger side is about an inch from the top molding (i.e. not closed all the way). With the window completely open, the driver side of the rear glass does not fully retract into the tailgate.

The glass appears to be firmly attached to the regulator arms on both sides. I read a thread about having to "align the regulator arms," but no information on how to do it.

Any assistance would be appreciated. Thanks!
