I bought a HD clutch plate from Chev's of the 40s about 5 years ago. It was a reman and I gave them the core I had. It wasn't too expensive. A little over a hundred bucks as I recall.
I had been running a 10-1/2 inch disc for several years before that but it was for a V8 and had a different number of or stiffer torsion springs than the six cylinder one so it always chattered on take up. It was all I could get at the time. I had an oil-soaked, 10-3/4 six-cylinder disc sitting around and had it relined locally. So now I have the right disc and PP. Works fine now.
I'm also running the six-volt, 9-bolt flywheel and matching starter. I've long-since converted to 12V and it has started fine for maybe 20 years since I had the strter rebuilt. At the time, I asked the rebuilder if they could convert it to 12V and the answer was "Why would you do that, they work fine just like they are." They've done a lot of other good work for me so I believed him. He was right.
