I wouldn't use an air too, you run the real risk of stripping the allen head. To install the Momo wheel, you just remove the original steering wheel. The hub adapter with the horn ring goes on and then you slip the rubber boot over the adapter, then you bolt the wheel to the hub adapter with the mounting bolts on the hub adapter. Because of the design of the Momo adapter, it's not that easy to line up the steering wheel and it may take some "trial & error" till you get it on properly aligned, so don't fasten the wheel bolts or the 10 mm hub bolt too tightly until you're set.
