os giken

So in my FJ20et motor I found a completely rooted OS Giken twin plate, and since it has a specific flywheel I cant justswap the clutch on its own for an HDCB like I'd planned. I want to know if anybody can help me find the part number for this clutch and figure out specifically what engine it...

I have for sale my old clutch off my sr20det. I replaced it cause it started making a noise.... but when i took it off it turned out to be a colapsed spigot bearing in the crank instead :mad:.. so the clutch was fine. Sale points: Its never slipped even with 400hp going through it. OS...
