I have a set of CP Piston rings for standard bore. These are BRAND NEW. There is ONE set that doesn't have 1 of 2 oil ring because that was used to replace a damaged oil ring during piston installation. However 3 sets are complete. $25 for SINGLE pack for one piston $20 for SINGLE pack for one piston with 1 missing oil ring This makes for good replacements if you need just one set.
