Attention: TDR Forum Junkies 
Speedometer quit working a long time ago.
I saw here that the Vehicle speed sensor might be the problem.
I replace the Vehicle Speed Sensor in the rear end housing and the speedometer worked for about 1/2 mile.
I stopped and moved the wires going into the VSS plug and the the plug that ties the VSS to the Wiring Harness and it worked again. This forum sure make fixing our trucks a lot easier so thanks for everybody help.
