John a +.030 piston measures around 2.136 so you must have a +.030. I don't have any new ones but I have a couple of used ones that would work. I am not sure about rings. I have a few but don't know the size. I could bore out a try piece and check rings by it. What I do with a used piston is to sand blast the top only and coat it with a heat barrier coating.. I have quite a few used +.015 pistons but only 3 or 4 +.030, they are kind of hard to come by. $35.00 for the piston and $55.00 if I clean and coat the top. Ph 660-775-2475 Good Luck Larry McAfee
