OMP streering wheel boss

Hi all picked up a nice OMP streering wheel thinking the boss was the same as the newer X1/9 wheel, but no anyone any ideas on the new boss to Mach both together ( X1/9 is no available)
So will an UNO one fit or anything else

Thanks

No, the bolt pattern on the late type Gran Finale steering wheel is weird, it does not match up to any aftermarket boss as far as I know (and believe me, I tried a few). An OMP wheel will use a standard momo boss pattern, and there were quite a few x1/9 specific momo bosses on the market they do come up on ebay from time to time, also Fiat 124 bosses do the trick if I recall correctly. The other issues to watch out when fitting an aftermarket boss is it often messes with the indicator self-cancelling mechanism so some fettling may be needed to get that to work correctly again, also make sure it has a wire and contact for the horn as some of them do not have these!
Finally once you've got all that sorted out you may find that the steering wheel is a few inches closer to your chest and that it is a chore reaching for the indicator/wiper stalks and you will think why did you bother in the first place!
