Hi stevel I'm afraid you'll have to be a bit more specific. Wings come in various sizes, shapes and more importantly various mounting systems. Are you working on a DIY foil or assembling one from various spare parts or replacing existing wings on a brand name foil... ?

looking at building something, just making enquiry to get idea of costs

One of the WA guys made me a set of carbon wings for my LF Fish - I never got them set up right and eventually sold them. He may have the molds still.

From memory they sold for maybe $500 for the set ? There is a huge number of hours involved, not to mention the materials cost. It wouldn't be a cheap option, seeing that other post about $500 complete foils now available from china.

pm me if you want me to put you in touch with him.

Slingshots entire foil system is modular. Surf Foil, Kite foil etc.

They sell all their wings separately.
