I purchased the aftermarket bumper at the big Iola, WI swap meet from a vendor who resides in WI. He was selling a large quantity of aftermarket Chevrolet sheet metal parts, including entire floors for some classics. He was also selling several generations of bumpers. I'm sure he was simply a distributor for one of the large aftermarket dealers, but unfortunately, I destroyed the cardboard box that the bumper came in, so I don't know the manufacturer. Sorry.
