Which 7/8 master cylinder?

I’m running Cass’s 15/16 manual master on the 70 Dart with Wilwood front disks and it works great.

Give him a call.

_1987 dodge diplomat, alum, 2 bolt, pedal feel is about twice what normal power brakes are. Used old splitter for the front / rear connection, no problems. Cut and thread original manual brake pushrod, put back together w/ a treaded rod coupling. adjust for adapter plate if u needed one to go from 4 bolt to 2 bolt . Weld , trim to look racy , before final install.
