Purchased the truck years ago.Completely disassembled it for furture use. Now it time to get it running. One problem I've ran into, it's a 4 speed. Chrysler added some kind of adapter on the Zee bar at the end that goes to the clutch fork. Might someone have one of these or know someone that knows someone that has one ???? Need to figure out how to adapte a standard torque arm to work.
Thanks in advance for even looking at this.
