I lost the manifold bracket from my original Genesis 1000 during a move years ago. I found it and didn't realize what it was until I decided to rehab the grill later on. So yeah, that's a thing. I knew they made Genesis 1000 manifolds with the hooks, like I said, I've seen them for sale. They were always square tube ones though. The manifold you show is a round tube with the hooks, that one I've never seen.
