Got a used ACT HD on marketplace, and I should have asked for more pictures because it arrived with a somewhat odd clutch disc. Seller told me he thinks it was the one that came with it, but it's obviously not. Disc is only marked as a Daikin (which I believe mfgs for Exedy), and made in USA. It also has rubber dampers instead of springs, which is a bit unusual.

Should I replace it? It seems like the rubber would make for a nice engagement, but IDK. Also seems like a potential point of failure under higher power levels (squishing, tearing, etc). I know organic compounds can vary a bit also, so who knows how it will perform compared to the typical ACT?

 

Ok, so it looks like there have been some ACT kits that came with the daikin disc's for some reason. On the Moss website, their listing for it even shows it like that. Theres also an 8 year old thread where someone else had found one like this. Anyway, I think it's safe to say that it will probably be fine.
