My Hemi is slightly forward to allow the factory Hemi valve cover to clear the factory A/C components, mostly the blower motor. Additionally, my car was an automatic, so I added the 4-speed hump which may or may not be in the exact factory location. While the GV came with an A-body adapter, I made the my own adapter plate to put the shifter exactly where I wanted it in the hole.
My first attempt was to modify the GV adapter, then I had one made from scratch. I recently stumbled upon either the modified GV piece or my first attempt the other day. Wasn't rocket surgery, it had to go slightly forward and over a tad to fit my application.
