1976 Mexican Spec Plymouth Valiant Duster

Didn't MX cars have different rallye wheels and center caps?
I thought even the hubs were different.

Is that a 73/74 US Duster grill? ...or did MX use that grill later? 75/76 grills are different in the US
It looks pretty similar to the US 1976 Valiant/Duster grille from the pictures on Google.

The rally wheels it is wearing are the original wheels to the car.
