Posting for a friend whos looking for a zx12 exhaust manifold to suit a westfield seiw.
He's also looking for an engine cradle to suit the same although i'd be surprised if thats an off the shelf item but you never know.

s&s headers in the states sell a very nice manifold which fits a zx12 in an Indy absolutely spot on. It's supposed to be for a dwarf car but just happens to fit. Credit to Macspeedy for figuring it out and being brave enough to order one, which I swiftly followed.
