Don,

I read somewhere that there is a company on the east coast somewhere that does it. If I could get the CI I thought I would turn it for a press fit and then pin it or key it, I think keying would work best. So far the only the only short pieces I can find are ductile cast iron and of course that won't work. I now have the 90 fins on the front with good liners but the rest of my drums need liners.

Jack.
