Rebuild Kit for Window Regulator L/RDid you know that you can rebuild your window regulator? Using our over stock of right hand regulators we drill out the press fit crank and gear bracket which can be used for either right or left hand regulators. Yes they are asymmetrical. In house we weld the press fit holes but you can also bolt or rivet (not recommended but will work). We do not require a core for this product. Gears are inspected to assure quality.
