Tilton 76-Series master cylinders have a upgraded body from the old 76 series master cylinder but still keep their compact design, and now feature 2 x AN3 (3/8"-24) outlet ports with a port plug so that if either of the ports are redundant then these can be blocked off. The inlet port is threaded 7/16"-20  to accept AN4 fittings when remote-mounted reservoirs are used.
