Yes, in my opinion, it does really matter. Did you ' just put it there so it could brake it down and be more simple for some other users...' Or.... 'break it down for some other simple minded users' A spade is a spade, as far as I'm concerned, and a BA is a BA, a BF is a BF and an FG is an FG. Ford did not, and has never made, a Mk1 Falcon. If you google Ba Mk1 or Bf mk1 you get no reference from Ford at all, only forums and the like. Anyone can speculate as much as they like but at the end of the day it is as it was released from the factory. Simple or not.
