alsom i didnt see you mention stock or a brand, so we have to assumne you mean stock.
i would bet all s13s use the same bolts (if you meant holding the press plate to the flywheel of course)
you can also take one (if you have one left) and bring it to a fastener storte (Ace hardware, whatever) and just match it up
if you lay one bolts threads against the other, if they mesh, its a match
im in the middle of documenting all the bolts for a 4AGE, and will do the same thing on the next CA i build (using all new bolts in the process, with ARP hardware for mains, rods, and head studs)
a really nice tool to have is a pitch kit. Usually will come in a unit like a feeler gauge, swiss-army style, with a bunch of pitch testers that you just hold to the bolt or hole and match it up, to find out the pitch. theyre only a few bucks and you can pick one up at sears. Then it will save time the next time you need to spec a bolt for a replacement (without having to bring a bunch of dirty bolts with you and keeping track of how many of each you need)

edit> almost forgot, the hardness rating. in metric its 10.x, in imperial its grade 8 (metric 8.8 is NOT equal to imperial grade 8, which is the hardest)
