Has anyone seen or used one of these

I did speak with a rep at speedmaster today. It looks like June is the earliest I’d see it. She said the P/N is still an active one but it’s currently semi-pulled from their site because “they don’t do back orders” which I’m not sure I believe. She also said there’s a few orders in for this manifold right now, so it sounds like they wait for orders to come in before batch making them. I did ask when the last time they fulfilled orders for these and she said two years ago. I’m not exactly hopeful with that last line but who knows.
