'67 Disc Brake "Control Valve"
 

I need a rear brake pressure control valve for my 67GTA (rear wheel lockup problem.) I've already replaced what I thought was the pressure distribution valve, (along with everything else in the brake system.) However, on 67's, the pressure valve is a seperate piece, mounted near the rear axle, just before the flexible hose that supplies fluid to the rear brakes. The part I need looks like just a connector, about a 3" long tube. Since other years incorperate the pressure valve into the distribution block, this is not a common part.
Any idea who would carry this part???

Thanks, Sta67ng@aol.com
