aren't the 96 and newer hubs 6 bolt, while the 95 and earlier 5 bolt ?
if so, that would be the reason RA would show a difference. or was that just for dakotas ?
another reason may be the retaining threads to the knuckle may be a different pitch or size.
i'm not a truck knowledgeable guy, just throwing things out there that may be a reason for not showing compatibility.
i have mixed and matched so many components over the years that should have not been possible, but only being able to do so just by trial and error, plus listening to what others have done with success.
this issue is interesting to me because i will be learning something new from others on a subject i know nothing about.
thank you to all that are participating in this issue. you are educating an old man in something he knows nothing about.
