small bore master cyl

Oreilly Auto has a disc drum MC Part # 10-1571 reman for $37.99 Bore Size (In): 0.937 Inch. Just put one in my 65 Dart still in process of bleeding and all that. The way it keeps snowing and cold won't have out till May :(
There's also a Raybestos MC a lot of guys recommend with a 15/16 bore, don't know the number off hand but I'm sure someone will chip in with it. Good luck
