My C60 manual says the master cylinder assembly is part # 5450260 (same as the C15A). The only master cylinder I see today at Chevs of the 40s that looks to be the same general shape as CMP master is part # 5450257, listed as fitting cars. I thought most cars and pickups had 7/8" or 1" master cylinders rather than the 1-1/4 usually found on CMPs.

Is more information available about you got and how close it was to the CMP master cylinder?

Chevs of the 40s do sell kits, but todays catalog seemed to be for 7/8 or 1" master cylinders.
