Your best bet is Twin City Outboard. <br />There's also a fellow on sellyouritem.com that sells antique Johnny/Rude parts. I got a few rings from him a while ago for reasonable prices.<br />Finding NOS pistons is going to be the hardest thing, and you might end up settling for used. That is to say, if your not going oversized, you should take a long hard look at the pistons you've got.<br /><br />Good luck!
