NIB 4701 cont motors corp pistons

[Stumpy]

Digging through my pile and just found a set of four brand new, in the original boxes #4701 Continental five-ring pistons. Mistakenly thought they were something else. I think they are for the A-80 option???....mebbe somebody can confirm that? Doubt anyone is going that direction with their T-craft but thought I'd offer them here before before they head for Ebay.
Open to swaps...Looking for C85 bits, an MA-3PA 4233 core, or ???
