    I had the same thought. Just haven't had time to research yet.

    I already own a set of '79 RD400F Daytona rims I'd like to use. I've heard the '79 Daytona triple tree can be used as-is on the RD350B. I"m hoping that also means I can use the whole front end, axle and all without spacers. I prefer 35mm forks, partially for the stability and partially because I have a GT750 35mm front end on my CB350 and it'd be nice to only need one set of spare clips-ons.

    These guys have tons of stuff. Give them a call, they may be able to help you. I have a friend with a vintage shop that gets stuff from them all the time.

    Potomac Vintage Riders Swap Meet in York is this weekend. Usually a big turnout. You may find what you need.
