Re: Steering wheels!
Buy the steering wheel and boss kit together. The boss kit generally comes with fitting instructions(at least the momo ones do) and a centre peice. Display ones occasionally get flogged so they do not display them with the wheel.
The hardest part is getting the old wheel off once the retaining nut is removed.
Remember to have the steering wheel straight throughout the whole process, otherwise when you put the new wheel on, the wheel may be off center.
I have done it in 10 mins, but it has taken a lot longer than that when the wheel did not want to come off. Borrowing a steering wheel puller is a good idea.
