rear window regulator
 

i put a new tailgate on my '88 and when i was removing the window from the guide rollers i broke one of the wheels.
it looks like the pins and wheels are replaceable, without replacing the regulator(which seem hard to find).
where (if they even have them) would i be able to find the pins that hold the guide wheels, and the guide wheels?:icon_doh:

found them lmc truck has everything.

lmc truck page 25 of the 1973-1991 chevy blazer/jimmy catalog

part number is 30-0498 ROLLER AND RIVET-WINDW REG 4.95$

hope this helps...
