So if we're going to take this topic completely off the rails, I think I still have some old Marsh recapped Goodyears in the shed that came with my '86 Nance buyout. They were too hard and heavy to run in '88, but if someone really needs them now, I could be persuaded to part with them.

We could also check Towel City. I think they still recap racing tires. Sounds like we've got plenty of casings available...
