since your taking pics-take one of the shaker cable hole on the firewall-see if it`s got the thick spacers on the trans mount and the spacers for the 15 inch wheels on the control arm rubber snubber things.
also the trunk floor spare tire hold down rod. some of these items are not unique to hemicudas but if something isn`t right it will open a can of something...it shouldn`t have wheel arch mouldings and the front fenders were modified on the upper wheelarch-that`s why it`s got a hemi fender tag. more than likely made later in the 70 year-i`m sure someone will have an approximate date when they started adding the extra tag i think it was about feb march 1970.
make sure you get the numbers from the engine and trans too.
all the best
