The Wilwood Tandem Aluminum Master Cylinder for early Mustangs is offered with a 7/8" or 15/16" bore and includes the correct pushrod for the factory 1964–1972 brake pedal. It matches the 3.22"–3.40" factory manual master cylinder mount, provides a 1.10" stroke with a 2:1 volume ratio, and is machined from high-pressure die castings for a lighter, direct-fit replacement on those classic Mustangs.
