Does anybody have a trick to get the rubber seal in the tailgate without braking it but making sure it locks/clips in?? This is the one on the outside of the tailgate window. This will be the 2nd time I bought it. The last one I put in and when I rolled it up out it came. So then I tried to take the window out put the strip/seal in and bent the hell out of it trying to get the window in. THANKS!! OH...its for a 1990 Blazer if it helps!!
