Hi gang! Been meaning to do this for the better part of two weeks now. When I was walking into the Phoenix AZ. fairgrounds swap on Saturday the 7th, I picked up some thing off the ground that someone might be missing. Just saw it sitting on the kitchen counter while making another pot of coffee and it reminded me to post this. The object in question is a piece of aluminum cut in a "D" shape about 4" X 2 1/2" and the center cut out and screened. Could be from a brake backing plate, could be from an induction system, and I can't think of what else it might be. It is fairly well made and pretty cool, so if nothing else I would love to see what it came from! If you bought something that had this on it and lost it on the way out to the parking lot, give me a yell.
