Getting my stock clutch replaced with an Exedy stage 1 and a Fidanza FW. Having the mechanic replace the RMS at the same time. I’ve got the new seal for that, but I’ve been told I need a pair of “half moon rubber seals” that are going to need to be replaced. I can’t find an actual part number or manufacturer and wondered if someone could help me get an exact part number. I’m trying to have all parts ready for him so I can get it back quick. The closest thing I found was on Rockauto and is a FelPro OS30696. Is that the correct part? One set good enough or two?

thanks in advance
