Ring sets like this get matched to a specific bore diameter after a rebore, so the 040 marking tells you it's meant for a cylinder that's already been taken out to that oversize. If you're not certain what size your barrels were bored to, it's worth measuring before you order.
Call the shop if you want us to confirm this is the right set for your bore before it ships. We'd rather get you the right rings the first time than have you sending a set back.
