Piston rings
I'm putting sleeves and pistons in an international C. Got three ring pistons but no guidance or marks on which way's up for the rings. The top and bottom are easy but the middle ring has a bevel on the inside. Bevel up or down?

Correct ring installation is critical. Only Manley rings, top ring has a shiny gray edge. When the top and 2nd ring has a dot, install dot side up. Unmarked top rings with an inner bevel install with bevel up. Unmarked 2nd rings with inner bevel install with bevel down.
