Description: Original Dated 1970 Chevelle SS 454 LS6 Disc Brake Booster Master Combo 9391 BBThis is an original HD brake booster, master cylinder, and proportioning valve that was taken off of a 1970 El Camino SS 454 LS6, but will also work for Chevelle. The casting number on the master cylinder is 5470409 and it has a stamp of "BB" in the semi-circle on the front. The front of the brake booster has a tab that I believe is stamped with a "9" and the rear side of the same tab has "939"(might be missing 1). The proportion valve has a stamp of "9 311". This is a "real deal" original 1970 setup that is being sold as a CORE !!! This will fit other years, but verify before purchase!
