We don't have much more detail on this one in our records beyond the oversize and set designation, so if you're not certain which bore size your barrels were taken to, it's worth double-checking before you order. Piston ring sets are matched to a specific bore diameter, so getting the oversize right matters more than almost anything else on the order.
Give us a call if you want to talk through what you're rebuilding and we'll help confirm this is the right set before it ships.
