On my 68 XR7 while disconecting the plug from the passenger side harness to the fuel sending unit I broke off one of the aluminum probes. The male connector where it goes into the female conector. Can and how would I fix this or do I need to replace that left side harness. The harness runs from under the dash, down the passenger side into the trunk where it is used for the trunk light and fuel sending unit. Also does the overhead panel and opera light inside the car.
