I won the bid on a Clock on Ebay and when I got it, I found that the clock on Ebay was 5 inches wide and my clock hole is 3 inches wide. I have a 1950 Champion. The seller has agreed to take the clock back, and issue me a refund plus shipping both ways, and in return I told him I would try and find out if it went on a Studebaker. If so, then I am at the right place to find out. The backside of the clock has a round area that is 2 1/4" wide, and that area won't fit into a 50 Champion hole either. The item # of the ebay item is 200008351635, which is not an active item any longer sinc I won the bid, but I am sure it will be back if the seller can find out what it is for. Hope yaw can help! Thanks!
