I have a 72 Challenger with a 318 and 833 4speed. I bought a pistol grip shifter and linkage but, my problem is that I am not familiar with the way the linkage and the trans levers are to be positioned. It looks as though the rods are going to hit the crossmember. I am also assuming the shifter mounts to the rear mounting position on the trans; otherwise the pistol grip will be too far forward. Can anyone enlighten me? Thanks!
