I have an 88 integra who's driver's side window regulator is broken.
Specifically, the little gearbox in which the window handle attaches
is pretty well ground up and ruined. It looks like this little
gearbox (about the size of a walnut) could be replaced with a bolt in
replacement. The original one is attached to the regulator with
rivets. Does such a replacement exist? Like from the little odds and
ends you might find in the "Help!" section of an auto parts store?
