I have one in my c-series 3/4 ton dodge pickup. I think wilcap might sell bells for it? With some time and a ruler almost anything can work I think.
Maybe try one of the weaker 5 speeds out of a mustang? Whatsitcalled- a RAPP or something? That might be cheap and light and run the gears real nice for a light car around 100hp 200tq.
Are you going to hotrod the motor? Headers, intake, carbs, milled or aluminum head? It might be best to go with a numerically low rear gear and a light car so that you can take advantage of the low rpm redline and torquey powerband with a 5 speed's low 1st for taking off.
