As title states I'm looking to find the stock under bucket valve tappet shim outer diameter. I've been looking all over and can't find it. Mine measured at 10.5mm, but it has some mushrooming going on so I'm not sure that will work or not. Not to mention I can't find 10.5mm shims 10mm I can. Please any help and I will be very thankfully
