Marsh old mate, how they turn it around to suit there agenda is they say they don't have to "modify" anything.....they mix and match components off different models to make them fit.....I'm with you, to me it's black and white...you can't take major components off the next era, ie pre85 forks in a EVO bike, pre 85 bikes are linkage bla bla, ....ie later equipment.....doesn't matter if its still drum brake, it's later equipment.
