does anyone have a diagram, or instructions on how to adjust the original auto console shifter on a 69 gto? also, I have the console out, and believe that I am missing a support from the front of the shifter mechanism that supports it. I am guessing it would sort of be a "block" that is fastened to the car floor, and the front of the shifter housing.  the shifter is not hitting the gears as marked on the console display, so some sort of adjustment is required. also looking to buy the plastic side marker/signal light housings that go in the front valence for the same car.

 wondering if I would be better off to go with an aftermarket shifter?  thx!
