Original 1970 Disk Brake Master Cyl / Prop Valve
 

Had this as a spare for many years for my 69 that I sold. Took it off a running 1970 SS car and it still has fluid in it. Codes are "5470409-1 1/8 * D6", "288". Has "BB" stamped on front and has it's original cover. The proportioning valve, line and mount bracket are included. Asking $250 or offer for all. Pictures on request.
