I went through some of this before, if you use a an SN97 wheel then you must use an sn97 wheel hub, same with going backwards to a fox style hub , The (as I recall) pre SN heels used a set of contacts for the horn while the SNs use a "tape" for lack of a better term. The hubs do interchange however on the steering shaft. As far as the 2006, it beats the crap out of me, but if the shaft is the same diameter/style, then I would assume the hub would be interchangeable as well, but that's a 10 year manufacturing cycle and a totally different body style. Ssso I'm saying not likely.
