window seal

[318idriver]

hey guys i have looked all over and i cant find what im lookin for, so heres the problem my drivers side window regulator has a gap in the slide where the window goes up and down on the track, the thin piece of rubber that is supposed to be against the window is missing, now main question do i have to replace the entire regulator to get the new rubber on the track or can i just find the rubber inserts somewhere and put them on? Any help is apreciated thanks.

I've never done this myself, but it looks like they just unclip from the upper door frame.  I'd figure you have to remove the outer trim & door panel to get at them.  Doesn't look like the regulator has to come out.

For my '89 four door it looks like part numbers 51211945591 & 51211945592 (Door weather strip inner L&R) and 51211913057 & 51211913058  (Door weather strip outer L & R).
