I already have. Over the years, there have been times when a box of parts or something similar just shows up. Sometimes years later I still haven't learned where they come from. Generally, when the random things show up without my knowledge, I will wait a few months to see if someone comes back to inquire about blasting, welding, painting, or whatever. After 3 months I just assume it was a donation, lol. Other times, I will be somewhere and just luck into a deal that only a fool would pass on, like the NOS door handle at a yard sale for a dollar. And because Mopar karma has been kind to me over the years, I don't hesitate to pay it forward from time to time.
