I'm replacing my broken harmonic balancer and in the process I mangled my harmonic balancer bolts, not my crank pulley bolts. Saw some on LMR but they are ARP and about $25 per bolt! I don't need all that. Just some stock replacements. Checked summit but couldn't fine some for any less. Also, headed to the NMRA race in Charlotte next weekend (I'm pumped), should I just try to pick some up at the swap meet? Any ideas and/or part numbers?
