On my 96 2500, inside the door cavity there is a clamp that connects the electric door lock shaft to the manual door lock shaft. The clamp is about 3/4" x 1/2" with a through hole and a slot with three screws that tighten on the parallel shafts. Both shafts are approx 1/8" dia with one being slightly larger. Is the a source for a replacement for this $0.50 part, or am I stuck trying to make one?
