Good eyes and find on the bumper build, Gaterose. Crozhawk bumper is almost a dead ringer for that one.
As far as if Crozhawk is still building them. The short answer is maybe. He moved and I know he just recently found a local CNC/laser cutting shop and he retrieved the bumper design files from the old shop.
So he has everything he would need to make the parts but last I saw he was gauging interest for the bumpers to be sold as a 'build it yourself' kit. You buy all the cut bumper pieces and weld it together yourself.
