PW - WINMOT - 89 Avanti right window motor is Chrysler # 04480326,  cable04445418.  If you need the 
plastic gears in the gear case body shops have kits to rebuild.  Good luck.  Hugh Severs '89 #534 Sep

 The gear replacement comes in a kit. Advance Auto Parts will have it, so one would assume that the 
others do also. Take your old gear with you to match the size and take the motor # there are two 
different size gears available. July 2008
