I talked to Patrick yesterday. He recommends keeping the torques tube rear although change to 3:55 gears or get one out of a Powerglide. Weak link is the stock 3 speed. With a truck bell housing from a 48-53 & a 3 speed Saginaw from a 66-77 Impala, you will have a good driver. Will need his adapter to convert tranny to torque tube output. Saginaw will allow the column shifter to work. Patrick is not into torch cut & toss, but rather keeping as close to original as possible. So I guess I need to decide which way to go. Sherman
