WTB - Shift and throttle levers for a twin-engine 1980s cruiser

[kingfisher23]

I'm looking for the shift levers and throttle levers for a 1981 310 Vanguard. I'd like to install original-ish parts if possible, but really any lever set that is built for non-electronic engine controls would work. My engines are inboards, so no trim switches needed.

Thanks for looking!
