This is a correct original style power brake booster & master cylinder for 67-70 Cougar & Mustang. The part number for the booster is 54-76201. These are typically $350+ as a remanufactured unit. 

This unit was in good functioning condition when removed from my '67 XR7 Cougar. It has been in dry indoor storage since then.

This is a complete unit with the correct pushrod and vacuum ports. It can be bolted in and used right away.
