Are Grant/ford Racing/ And Momo Horn Button Interchange ?

So I picked up a near mint perfect 86-89 saleen veloce steering wheel today and want to toss the momo horn button for a ford oval black or blue, it doesn't matter which, does anyone have any idea if a ford racing horn button will pop on this wheel? or the grant/NRG/sparco? I know momo horn buttons pop up on ebay time to time but it will be easier to order a $20 horn button than buy the real deal, let me know please

So I think I answered my own question, after looking on line at summit racings line of horn buttons for grant wheels, a guy on a review for the ford blue oval grant horn button said it fit his momo wheel perfectly, for $20 shipped I will give it a go..
