The simplest approach is to put an ad in the "parts wanted" forum for a Fram or AC canister filter. Yes, if you put a much less efficient spin on filter on you'll need to restrict the flow. Tap one of the ports on the adapter for a pipe thread, put an Allen pipe plug into it, and drill a 1/16" hole into the center. Don't scrap the Frantz filter- - - - -some of us can fix them so they don't leak, and I'd love to have one.
