There's only one place it can go, and it's very logical. Just to the left of the e-brake handle, next to the kick panel. If you notice in your pic, the top of the plastic bracket on your release is angled. I added one to my 73 Challenger. Look under your dash. You will see exactly where it goes. The underside of the dash is shaped with the same angle as the release mount, and you will see two screw holes, which will align with the two holes in the release mount...
