Nope. The AM and AW guts are different animals. The AM is similar to the FM/FW in design in that it uses compound planet pinions. The AM also uses a specific 54t gear ring while all the other SA hubs use a 60t. I found out this little bit of trivia the hard way.
I think that the AN hub being referred to may actually be the AC or AR. Rarer than gold plated hens teeth. They may be one and the same, too.
