IGot a 60 F-100 I am on my second new NAPA brand clutch master cylinder and the 3rd one I re-kit my self yes I honed it dead straight checked the bore no pits left not over sized assembled it with fluid and it is leaking into the cab floor again any one have better luck with another supplier or are they all from the same place just in a different box. 

I just purchased both the clutch hydraulic cylinders from O'Reilly and they are Chinese. I suspect that is gonna be the case anywhere you buy them. Don't have mine installed yet so won't know the outcome till later. There are places that sleeve them with brass (Whitepost Restorations?). Were your kits American made?
