That one is good if you have a power brake booster or like a rock-hard pedal! You may want to consider a 15/16 bore master cylinder. A little more pedal travel but much better braking! Just my 2 cents.
I have an aluminum 1-1/32" bore master on my 68 GTS with SSBC aluminum calipers in front on KH style replacement rotors. Rear brakes are stock. It stops excellent from over 130.
