To add another version of this front disk / stock rear brake setup i used the following:
'70s GMC 3/4 ton master cylinder (1 1/8" bore) with an adapter to keep it under the floor.
Speedway disk brake kit (the one that retains 5 on 5 1/2 wheel bolt circle)
2 PSI residual valve for the front disks.
10 PSI residual valve for the rear drums.
No proportioning valve.
The adjustment of the rear is somewhat critical, They cannot be setup too loose.
Bleeding was done with a homemade pressure bleeder. A vacuum bleeder did not work for me on this system.
This system is now 9 years old. I have had no issues with this setup.
