Hi. Does anyone know for certain which (if any) steering wheel boss can be used to install a Momo/Sparco/Nardi type wheel? A lot of the traders on ebay claim the 156 boss will fit (like the Momo MK4035R), but a check on the manufacturers website says otherwise. I'm not concerned about airbags as the car is for track-day use so all of them are now removed. Cheers.
