I am, after an original master cylinder for power brakes to fit my 57 retrac. I believe they have a 1 1/4 bore size :002: :002: :burnout:
1 1/16, Llincoln 52 to 62 uses the 1 1/16 master.
They show up on ebay all the time...$70
Theres one on ebay now with a 1 1/18 bore . Is that ok for the original power brake s
I believe 1 1/8 is the correct size? Was told that by a fellow board member I purchased a power brake setup from.
