Get the power tracks and power wire that runs from the seat to the fuse box from any G-body in the junkyard. Might as well get 2 and have them both power. Seat should recline.
Both are the same. The pwer units for a bucket seat. Does fit a bench seat.
I had to do this because the reverse mototr on my Limited died.
Found a donor car. simple bolt in.
Also the backs are adjustable. Hope this helped.
By the way anyone know how to get a motor for the 87 power seat? Hate seeing a complete track and hookup. sitting because of a bad reverse motor. THIA...........ROB
