Dennis,
Good question. I know my dad removed the 3 speed back in the 70's and put the shifter to the floor. I am thinking that is when he used the 2 piece driveline. My problem is the 3 speed tranny is longer than the 4 speed that is in the truck now. If I kept the 2 piece, the driveline coming off the tranny would be very very short. When I get to that part of the restoration I am sure I will figure it out. Thank you for the thought! Jon
