I need to find a single set of .30 over rings for a 302. I have a set of moly rings that I chipped a ring on and had to buy a complete set to replace. I need to find someone that has done this and has 7 sets of rings left in the box. I have sealed pro moly rings-5/64, 5/64, 3/16. I am building my second motor and don't want to buy another complete set. Someone has to have these and help me out...
