1947 Case VAC 3-3/8 rings

[Pace F20s]

I need rings for my late grandpa's '47 VAC. The block casting number is VT149. It has aluminum pistons. The bore is 3-3/8". It has the normal 1/8" compression rings (3) and 1/4" oil ring (1). I haven't been able to locate 3-3/8" rings. Everything is listed as 3-1/4 or 3-7/16. Does anybody know of a parts supplier that might have that size?
Thanks, Roland

Have you checked at NAPA?. Email Don Livingston ([email protected]) the part number off your piston and ask him

Take a look at Sealed Power # 5456KX. They look to be what you are asking for, and listed for VAC with 3 3/8" bore.
