are dodge dana 60 and gm dana 60 knuckles interchangable?????

Not to be an ass, but you should read the "Dana 60" bible by BillaVista. Pretty much all the info you need to know about Fords, Dodges, and Chevy's.

Should have done a search first --but yes they are [assuming trunion style]-the tie rod holes are a little different with the taper. but a reamer can fix that.

Thanks for the info.
