Description
A manual window that fights you or jumps in its track usually means the regulator is worn. This right side front door manual window regulator restores smooth cranking on your 1977-87 Chevy or GMC Square Body truck.
It supports and guides the front door glass through its full travel, giving you the easy, even motion of a fresh mechanism. A correct-fit replacement that gets the passenger window working the way it should.
