mountney do a hub to fit the Bis, mine was about 16 quid but that was last century, the wheels are cheap if you look around, my wheel (brand new leather) cost a fiver in a clearout at a local auto factor. a couple of quid for the fiat badge of ebay and you come up with something like my avatar. You could go the momo route but it costa lot more, but if you decide to i've got a 308 GT horn push that would look peachy on a 126 (i got it for mine but it would not fit the mountney boss).
