I got a 4bt that is currently in a 79 chevy 4x4. It has the factory chevy 4-speed bolted up to the cummins. I have now decided to put the motor into one of our jeeps. I dont want the 4 speed in the jeep. I would like to put a 700r4 but am having trouble finding a flexplate. I would consider a nv4500. I also have a 47rh out of my 12 valve. What have you guys done or heard of?
