Red Alert returns

[PeteLeathersac]

I remember reading this a few years ago but forget so can someone please clarify;
Was the car's nose sheetmetal always a '70 and only the models kits got updated styling like the '72 style shown above?. Interesting the '72 nosed model kit shown still has '70 fenders..
Did the models kits w/ updated noses have the 71/72 style rear bumpers too?.
