so... i have a interesting question. i have a 71 413-HT. i need to pull a couple of pistons out to clean out the bore. my only problem is the rings. i dont want to re-ring the whole engine, just the two pistons i need to remove. my brother has rings that are the right diamater, the only problem is that they are about 1/64th too thin. is that going to be a problem, or can i get away with using those rings? thanks for the help!!
