Brake Safety Switch for 68 Dodge Dart

ok....I need a Brake Safety Switch (BSS). It must be OEM or used in very good condition. The one from InLine fails to pass brake fluid to rear wheels. My original OEM BSS is buggered up due to many on/off sequences of the F/R brake Ines...its a long story!!!!BBS must be in good condition, no cross threads, no mashed internal flare ports. You can check center position of internal shuttle valve with ohm meter, shows "open" for center position. Will pay reasonable price and s/h to VT. BSS is for 68 Dodge Dart SL-6 drum brakes.
