The canonical description ties this to the 67-74 range and the +060 oversize marking (JCC), which tells you it's meant for a cylinder that's already been bored out .060 over standard, not a stock-bore piston. When you're ordering pistons for a rebore job, matching the oversize stamp to what your machinist actually cut is the part that matters most.
