As far as being right, they did not make a split grill they have always been split grills since the 60’s. Every Pontiac has a split grill, whether it is functional or not.
Finally not all Pontiacs have shared Chevy engines, that did not occur until the late 70’s and early 80’s. In fact some of today’s Pontiacs use an engine from Opel or even Holden. Pontiac only has one model that currently shares the similar body components as Chevrolet. Glad to clear that up for you.
