If you don't want to work on it, use a racing rag disc and 2000-2400 pounds of static pressure and let it go.
If you want to have some tuneabililty you just need to suck it up and buy a Sof-Lok from McLeod or one of several clutch folks.
I use Cale Aronson but I think Hyatt is still going and Rob Youngblood is a good guy too.
Or, you can order a Center Force clutch. I hate them but that's just me. Any bite and they are parts eaters. You are better off learning to engage a clutch for performance. You can't slip it as is often the term used. Slipping is bad. Clutch application is good. They are not the same.
