The WEVO Stock 911 PSJ is a direct bolt-in replacement for the original Porsche shift coupler used in 911's from 1965 to 1986 and 930's from 1975 to 1988. 

The transmission side of the joint is attached to the transmission using the original M8 conical nosed set-screw from the stock coupling. The shifter side of the WEVO Stock 911 PSJ is inserted inside the shift tube, using a stump with O.E. style parallel knurling and is retained by the original pinch clamp. As an alternative, WEVO also offers a replacement Billet Clamp (available as an option in this listing). 

The joint is zinc plated for corrosion protection and comes lightly lubricated and ready to use. The WEVO Stock 911 PSJ can be installed and adjusted in minutes.
