Correct, I used a Tilton 600 series with their master cylinders and bias adjuster. Let me know if you need master cylinder sizes and I can look back at my records. The biggest tip I have is to get the "underfoot" version that has the front mounted master cylinders. That wasn't available back when I got mine but it would have made the install much easier. Even with my seat moved back about 10" the pedals barely fit in the right spot without the masters hitting the firewall. If I was a taller guy I'd have issues.

You will also have to figure something out for the throttle pedal position sensor. If I remember correctly, we used a GM sensor and machined a bracket for it, then used a standard linkage. You could also theoretically use a linear pot:





Here are a few pics of the mounting. They created channels with pieces of flat stock so the entire box can be loosened and moved forward/back. Plenty of different ways to do this, you just have to make sure it's rock solid. A lot of pressure goes through the brake pedal so you can't have ANY flex anywhere.









Oh and one more tip. Since you have to run all new lines anyway, install separate brake pressure sensors for the front and rear circuits. This will help dial in the bias, as well as helping you examine your driving after the fact. You can see how much brake pressure you used entering a corner, compare to wheel speeds to see how much pressure you can use before lockup, etc.
