What size master cylinder

1970 SuperBee, using Wilwood front disks part # 140-11021-D and rear disks part # 140-7144-D. I am using the stock Bendix Tandem Diaphragm power booster and would like to know what size master to use? The car is a street car not a race car.

Thanks

With power you should be able to push a 1 1/8 bore master pretty easily and it should have the volume for your setup. You should wait to hear from some others though, I never had wilwood stuff.
