Hi Ron, thanks for the information. I had already called several of the sources you mentioned. I finally called Mike LEMPERT, the maker of my steering wheel. He told me that the 7 series 2 has the same diameter and splines as a AH Sprite series one and two. I ordered a hub for the Sprite and it fits perfectly on the 7’s steering shaft. That problem is solved. My next problem is the big nut that holds the wheel on. I’ve tried a 14mm coarse thread, fine thread, and very fine thread. The threaded area is 14mm in diameter on my gauge, but is there another thread type I should try? Thanks, Bill
