1979-80 Cadillac Buick Chevrolet GMC Oldsmobile Pontiac 
*The same coupling is used on both the driver's seat and passenger seat.

Proper Parts has re-engineered an improved design that ensures a smooth slip fit to the motor and transmission. The D-shaft openings are very accurate. One end accepts a 3/8” D-shaft and the other end accepts a 5/16” D-shaft. It is 1.25” long (31.5mm). 

We manufacture these couplings from a urethane chosen for its hardness and toughness while still having good flexibility. When the seat comes to the end of its track there is no cushion, and this coupling allows the motor to slow down gradually ensuring a longer life for all of the components involved. It is much better than the original.
