Brake proportion valve

[Garner22]

Looking for a brake proportion valve for a 73 Duster with disc/drum.

A used valve that lays open will rust inside just like a master cylinder or anything else with brake fluid in it. Good luck

They look original and have them for all years. Kind of pricey at $89.00 but brakes are a place I wouldn't want to skimp.
