FWIW, if you've got a good Formula dealer to work with, a lot of these small parts are reasonably priced from Formula. Might not be worth it for just these things when you find an alternate source. But when I ordered some switches for my 311, I tacked on some of these, plus the rubber feet for the swim ladder, plus the bumpers on the engine hatch. Less than $10 for all that. I tried McMaster and couldn't find the feet and bumpers exactly.
