I will be buying a duel , none power master cylinder for my Ivy 63 project. I have an aluminum piece on my other one that I really like, but can't find who I bought it from. It is a 1 & 1/8 in. bore size and I'm running all drum brakes. I will be doing disc / drum or disc / disc on the new car. Can I use the 1 in. bore size master with the is configuration. Seems to be easier to find the the 1 & 1/8 in aluminum.
