Nardi are the same bolt pattern as Autotechnica if that helps.

I have 2 Nardi wheels and I have a proper Nardi boss on one and a 'generic' multi fit boss on the other that I got from ebay.com.au

Yep you got it, get a nardi bosskit if possible but if all else fails drill your new nardi, dare ya! ouch!

yeah i see, you know how you say the bolt holes are smaller on the Nardi, well i would need to purchase the Nardi boss kit right else i would need to make the holes in the wheel larger?

Damn so tricky, wish i could just screw the new wheel on lol never that easy haha :P

I bought a genuine nardi bosskit from ebay usa late last year. I don't know if you can get them new or anything.

The wheel will fit on a sparco/momo pattern bosskit but the boltholes in the nardi wheel are smaller, M5 or M4, not M6 as most wheels and the centre hole is larger than sparco etc so finding a horn button is interesting, Ive made up some alloy to sit in there on the racecar.

I bought a Nardi wheel and i need to get a boss kit to match the wheel/ my datsun 1200 ute 79 model.

Where would be the best place to get one?

Any info would be great, cheers
