Hi I just found a source that can supply steering hub adaptor for 2002, CS, Bavaria, and E12, E24(up to 83). This steering adaptor works for multis-wheel manufactures, such as MOMO(ABIRTH, ALPINA), NARDI(PERSONAL). It is made in Japan, and the price will be around $60.00.(including shipping). If anyone needs one, let me know. I will pick them up while I visit Japan this summer. I will most likely will bring some Nardi wood s-wheel as well. Jack
