There were no markings relating to size on piston I took out. I had to measure with a caliper. Once you have the size you can look up if it is standard, oversize, etc. If you have a shop in mind that is doing the re-bore, they would probably measure for you if you do not have caliper. Good luck. Link to comment Share on other sites More sharing options...
