For those Nova fans that are looking for a new or reman dual master cylinder for their drum brake 67/68 Nova, here is the second design snap bail unit. For Nova's with standard or power drum.  This second design replaced the first design "single bolt" for early 67 Novas. Ready to install. These units are made by either Wagner or Eis. Made in the USA. New old stock! This unit was used in the Nova up to 1970 with drum brakes. This unit will cover 1967,68,69 & 1970. Four wheel drum only!
