I’m converting my 71 Duster to 73-^ BBP disc brakes and 11” BBP drum rear brakes. The car will have manual brakes, and I’m trying to determine what master cylinder I need. I have a leftover new unused DBMC10 from Right Stuff, it lists as a 1.063 bore size. It was bought for a power brake 73 340 Duster we built. I was under the impression that power vs manual masters were different but recently found some saying they used the same master on a manual brake car. Am I correct or will it work for my application? Thanks for any help you can give.
