Purchased an original tuff wheel adapter for my 71 Demon from e-bay, listed as fitting A or B body, went to put it on today and appears the splines are different. The adapter splines appear smaller/finer and do not have the master spline. Is there a difference between the 69 and earlier steering shaft as opposed to the 70 and later? Did a little research and all I came up with is some conflicting information on Little Red/Warlock/Cbody adapters. Would like to positivly identify the one I have so I can resell. Thanks.
