Need a proportional valve 75 dodge dart

Posted a ad up sometime ago, **** happens, :banghead: :burnout:

Anyways,

Pulled out the slant/904 and did a overhaul, cleaned out the engine bay redid the wiring harness, floorpans , subframe work, car is Ready to be taken to the body shop, LAST THING I NEED IS A PROPORTIONAL VALVE, anyone got one for a 75 dodge dart 2 door hardtop, tried to rebuild it but that didn't go well as planned lol,FRONT DISK/REAR DRUM thank you and Mopar 4 life :burnout: :burnout: :burnout:
What seems to be the problem?Did you just screw the valve up? reason I am asking is its not always a proportion valve fault.
