I have a Hudson 308 that I am rebuilding and have an original NOS set of 0.01 over pinned pistons but have been unable to locate 0.01 over pinned rings for the pistons. I have located a new set of 0.02 over pinned rings and I was planning to file fit them. I realize that the circumference of the rings is slightly different but they seem to fit in the 0.01 over bore fine. Does anyone have any thoughts on me using the slightly large pinned rings this way? Failing this, I will need to buy brand new non pinned pistons at 0.02 over, rebore the block to 0.02 and buy new non pinned rings to fit.
