$1,234 · WANTED Capstan pinch roller and cap for Akai M7 reel to reel recorder

WANTED Capstan standard pinch roller (and cap if you have it) for an Akai M7 / m8 reel to reel recorder. The same roller and cap seems to be used on the Akai 300 series and Roberts / Rheem 700 series decks. I tried an Akai 365 deck pinch roller and it works just fine. What have you got?
