Need some guidance on master cylinder sizes

[2FAST4U]

Building a mK4 roadster
Engine small block Ford
Front brakes: 94 Mustang GT
Rear brakes: 94 Mustang Cobra
Pedals: Wilwood floor mount 6.25:1 ratio

From what I can determine with the information available, which isn't much, I come up with 5/8 bore for the front and 3/4 for the rear.

Any help is greatly appreciated

Bill

Good Morning Bill!

The 3/4 inch master is for the front, 5/8 inch is for the rear!
