Throw 'em out?

I would hold on to them but then I hold on to everything. You just never know when you might need them. Years ago I bought a 68 that had small to big bolt adapters on the rear and a huge pair of Cragar SS wheels and white letter tires. I sold those to a guy who was building a 3 wheeler for almost what I paid for the entire car. I just happened to have stock wheels here to poke under it. Still under there today.
I once tossed a reverb audio unit that came in our first 67 fish. I had no idea it would bring a fist full of dollars someday.
