Okay my buddy is scrapping his truck tomorrow. My brother wants to swap out door glass and window regulators because from years of vice grips, his crank splines are stripped out. How do you remove the manual regulators and glass? I read online that your aupposed to roll the window all the way up and secure it, unbolt the 4 bolts for the regulator, then it says to slide the regulator rearward to get the rollers out of the track. But,.i can move the regulator rearward because of the crank stub coming through the door. Can you guys help me out?
