This thread has been really helpful. I have what I thought was a 48 New Yorker however I purchased a 48 steering wheel part # BH1122313 as a replacement as the steering wheel on my car # BH1330991 was in rough shape and I found the 48 steering wheel I bought on ebay does not fit with the smaller diameter hub splines. So perhaps my New Yorker is actually a 49, which could be possible. When I resealed the axle the date stamp on the ring gear was 11 48, late production run perhaps. So I have accumulated steering wheel parts for a 48 which I cannot use. I refurbished my original 49 wheel and now is way better than what it was, but I need the horn button and hardware for a 49. From what I have learned the three legged spring retainer is not the same 48 to 49. Does anyone know if the gizmo for the horn ground wire is the same for 48 and 49? I thought about having the splines punched out on the 48 steering wheel so I could use that since I have all the hardware, horn button etc. but in speaking to a machinist this is not really feasible. I thought about going to an aftermarket wheel but I cannot find any matching hub adapters and I would prefer to keep the stock wheel with the larger 17" diameter as well as the look with the Chrysler emblem , horn ring etc. So any help sourcing a 49 horn button and hardware would be appreciated. If anyone is looking for a 48 steering wheel let me know. Cheers,
