Prepping factory k-member for race duty

"oldkimmer" in Saskatchewan has a set for sale, and the photos show BIG washers on both sides of the K frame. He's a great guy. I've bought parts from him for years, and always more than satisfied. Come to think of it, I might get that set from him. My goal is to replace everything at once with new/rebuilt parts and my new 408.
I'll most likely make some at work, we have some that are close, thank you !
I just sold a front disc set up that was all rebuilt & bought a rebuild set up for another set I have, which I'll get all cleaned up at work soon, hot tank & glass peen.
Wanna get this done asap, my 470 is coming home next month from k&k & still have a **** load to do on the rest of the car
