They are metal bushings wrapped in a hardened plastic/rubber compound to reduce NVH. That compound cracks and rips over a short time. It's also flared out on the inners that connect to the tranny. I found some full nylon spacers on grainger I am picking up tomorrow to see if it will be a reasonable replacement. They're kind of like this: https://www.accu.co.uk/857-cylindric...29=15mm&page=1

I am skeptical on brass because it might be harder than the fork hole material and wear/stretch it out over time. Haven't been to the machinist yet to get their opinion on a proper metal to use. I think Gen6cyl mentioned an alloy, and that's probably the way I'd go. Will take me a couple weeks to sort this all out and will report back if I have any good news.
