I have continuing problems with my three speed floor shifter. It seems the plastic 'ball and socket that it pivots on wear readily and then the shifter loosens up and hangs up. Does anyone know of a fix for this problem? Also need the plastic inserts that hold the window glass to the regulator on a Gremlin as mine are shot and my window sometimes falls, sometimes jams when operating, so most times stays up. This is real hot here in TX in the summer with no AC. Must fix these two problems as this is my daily driver. Who would want any other??
