Back in the day they called them custom steering wheels and they required what was called a horn kit to install them.Basically a hub that went on the steering post that the wheel bolted to.You might check JC Whitney,Jegs or Summit for a horn kit.As far as your airbag I don't have a clue. You might check eBay there could be some new old stock still available.The hard part was they had to match the type vehicle you had.Good luck with that.
