The Wilwood Tandem Aluminum Master Cylinder for early Mustangs in ball-burnished finish includes the correct pushrod and is available in 7/8" or 15/16" bores for use with 1964–1972 Ford Mustang factory manual pedals. It matches the original flange dimensions (3.22"–3.40"), uses a 1.10" stroke and a 2:1 volume ratio, and offers a lighter die-cast alternative to heavier OE iron units.
