"Early A" doesn't cut it

the '73 cars have a sturdy batch of differences from the '74-'76 cars, and the '73-'76 cars are different in a bunch of ways to the '68-'72 cars.
Well, see, if we get into the mechanical and electrical systems, I would say the next big divider after 67 would be '70 and insome ways '75 and particularly '76 are one offs. On the other hand not many '76 A-bodies made, so maybe we banish them to For F Bodies Only forum. laugh2-gif.gif
