I have got Manifolds ,Risers ,Adapters from Stainless Marine.
Everything is Brand new never used, still in the box,had a pair of them a while back, re-powered and I have no use for them.Collecting dust in the barn, if anyone needs them give me a shout I will make you a hell of a deal.I have 4 of everything.I think I have the gaskets for the risers not the manifolds.
