I am putting a 302 in the car and want a manual trans. Will the mustang T5 shifter location work with a bench seat?
You might want to check into a T5 from an S10, I think the shifter is farther forward. I'm using the 302/5 speed from an 85 Mustang in my 56 and the shifter is about 18½ inches from where the trans hump angles up into the firewall. I have buckets in mine so I don't know if the shifter would interfere with the bench seat.
You can use the tailshaft from an s10, they all interchange. I've got a mustang t-5 behind a Y, and I moved my seat back about an inch. Its a tight squeeze in there
I put a T5 in my '53 Victoria. Using an S10 rear case, the shifter will be quite a ways forward, so you'll have to use a long stick. The longer the stick, the longer the throw between gears. If you use a Mustang or Camaro rear case, the shifter will be practically under your seat. BUT --- if you can find an Astro Van rear case, the shifter will be about halfway between those two, perfect for our cars. A standard S10 shifter will bolt right up to the Astro Van rear case.
