I want to buy custom 1973-76 front disk rotors redrilled to small bolt pattern 7/16 lugs

I will put the 1973-76 front Disk brake factory set up on my 1967 Barracuda. Want to buy and use tubular UCAs, reinforced LCAs, and custom small bolt pattern disks instead of factory OR large bolt pattern 8.75 rear axle shafts. Want to buy the prop valve and brake master with or without booster - what do you recommend? I live in Southern California.
Doctor Diff offers a kit with the late disc setup redrilled to the 5x4" pattern, as well as all the peripheral parts you'll need for the conversion.
Be aware when you're shopping these parts that the late rotor also needs to have the bearing hub turned down to fit the 5x4 center register, and not just the bolt pattern itself redrilled. The Dr. Diff kit handles that.
