Actually it's a 1946 Dodge dump bed pickup. With a 1991 Shadow 2.5 Garret Turbo engine (mounted north and south). Right now I have a Dakota 5spd manual. But would like to have a automatic with overdrive.
That makes a big difference!! I thought you were working on an A body. I don't know about any clearance issues you might have with the A500 or the 2004R but I do know that the 2004R does not require any cutting on the trans tunnel on an A body.
