Greetings to all, If anyone is having trouble finding a worthwhile replacement for the "power seat transmission" GM parts 20225150 and 20114336 used from 79 to 88, please look here. ProperParts.com These units were made of nylon and the cases had a bad habit of disintegrating and the gears falling out. I have redesigned the case and had it professionally injection molded. The case is guaranteed for life and the internals for 1 full year. With over 100 sold, I am confident you will have NO Problems. Alex
