In need of a set of piston rings for A65 .015" oversize

[Tom G]

At my annual this year one of my cylinders was down to 24psi. When the jug was pulled they found a stuck ring and it turns out that at my last overhaul they used standard size rings on a .o15" oversize cylinder. The cylinder is fine but i understand that rings in this size are no longer available. If anyone has a lead as to where i might find a set i sure would appreciate it. Short of finding the correct rings i'll be going for a new cylinder. Thanks,
