When my dad and I bought a guy's stash of 18 spline stuff, I just used an old Hays B&B and Ram bronze puck disc that came with the transmissions. I figured, that we bought it and we had it. Gave me a chance to drive it around and see what I liked or didn't like.

Then I found that the pressure plate was not flat and burned up the disc after a bunch of abuse by me.

Either way, now I know what I want and what feel and I bought a brand new B&B / Long style McLeod disc that you can even add counter weight to. I got a McLeod 600 series disc. This setup is supposed to be good to over 650hp and guys are running even more than that. Very Very streetable, as that weighs even more heavily to me!

Scott, you're doing it right. So try out what you have and go from there!
