Thanks all! Wally.

You can use a stock 4-wheel drum distribution block. I'll be using Dr Diff's 15/16" master cylinder with the adapter.

I have 6-piston and 4-piston Wilwood calipers and run a manual 15/16" MC. The 7/8" was a little too much pedal stroke. The prop valve I use is Wilwoods as well and comes with pre-bent lines. Check you have fenderwell clearance. 1972 Barracuda - 5.7L Hemi, T56 Magnum 6spd - https://www.facebook.com/GoodysGotaHemi 2020 RAM 1500 [img]https://i.imgur.com/v9yezP9.jpg[/img]

Check you have fenderwell clearance. That’s the setup I was looking into, damn that sure looks nice. Will probably go with the 15/16” bore. Thanks Goody!
