47 chev, another option is a New Process A833. They were used in the 81-86 Chevy trucks. It's a 4 speed manual and fourth is an over drive. No electrics. It looks like a Muncie on steroids. If you find one, get the linkage with it. I'm collecting parts to replace the 465 in my 68.

I don't own a vehicle that isn't old enough to drink.
