Odd question about Dusters

Funny, I would have said '71 because that is when most of the upper end MOPARS changed their body styles such as the charger and challenger..however, my mopar history is sketchy at best.

I wish my '75 had disk brakes as standard. And now I use 1973 as the cut off for buying suspension bits,etc..

Fundamentally, wasn't the Duster body (doors, hood, trunks, etc.) identical from 1970 to 1976 so the profile was the same ?
