I found this information heresome time ago about using a 65 Chevy brake light switch in a 65 Mustang. You remove the brake pedal stop and place the switch in its place. Move the wires over and you're done. It is a bit difficult to install it, but nothing like the original. I'm 6'2, 240 with 3X hands and it is extremely difficult for me to work under the dash. This was a big problem solver for me.
