For piston rings I would try Grant’s piston rings, they were the only supplier I could find that had the wide 1/8″ compression rings in the configuration I was after (inside bevel instead of taper face tip compression). I think most of the compression rings for these engines were stock produced for Allis Chalmers engines that called for taper face, which is one step in technical improvement for oil control over the original plain rings used in the Pierce. If I remember correctly it was possible with Grant to buy individual rings instead of buying complete sets for other engines and having to mix and match to get the desired combination.
