various air filter housings

I have several air filter housings, that I don't know what they go to. Some single barrel, some 4 barrel. If there's anything anyone wants before I throw them out please let me know. I'd rather have them used if I can. They're located near Greeley, Colorado. I'm guessing $20 each, but will make a deal for more and it's obo. If someone knows one is worth saving but doesn't want to buy it that helps too-at least I'll know to set it aside. I don't want to store all of these. Pickup here would be fantastic.
Thanks,
David
