Still searching, but not really coming up with an answer.... well at least not a clear answer.
I'm using a mid 90's Ford truck hydroboost on my 69 Ford Cummins conversion and need to know which master cylinder to use? I have a rear disc brake conversion, along with 78-79 D60 front discs. When doing a part search I'm getting different MC bore specs (1.125" - 1.375"), any input, model year, application help would be appreciated!!!
They are so close just use the one that came with the hydroboost. I have tried everything from 7/8" to 1 3/8" on my truck with 4 wheel discs and there really isnt much if any difference, the bigger master stops a little better but either way I can throw myself into the windsheild so easily its crazy. You will love the hydroboost it blows vaccum boost out of the water.

Thanks for that input.... I picked up a late 90's MC with a 1.250" bore, so sounds like that ought to work out.
