I find myself with an extra brake proportioning valve. Made by Wilwood, and marketed under the Summit Racing logo. Brand new, never been used. Black billet aluminum with black adjustment knob (that say's Wilwood). Mounts with two bolts, comes with two adapter fittings. Allows you to fine tune the brake bias between the front (disc) and rear drums. Comes with detailed instructions. $40 shipped to U.S. PayPal is cool as well.
