Went with a GM 4L80 with a Mopar bell housing adapted to it. It's a stage V from RPM transmissions. It fits the car very well and has a stand alone tuner for the trans which plugs into the HOLLEY DOMINATOR wiring kit I'm using. I'll try to post pics later. The cars previous owner cut the floor for a modern 5 spd and the 4L80 is much smaller so....need to fab a tunnel now.
