For those Nova fans restoring or refreshing up their 1962-66 Nova, especially in the brake department, here is our brand new single master cylinder for those years. Brand new, ready to install. Also comes with the rubber push rod dust cover. This particular master fits numerous model GM Cars and Trucks. The 1966 Nova was the last year GM used this master cylinder till the Feds made the "Big Three" move to dual master cylinders for better braking and safety in 1967.
