Manley,
I once saw a display gmc that had a Chevrolet grill bolted into it. Mind you I wasn't about to go look closer as that would have required fence jumping and trespassing! Of course there was a big gap where the gmc hood rose up and I can't recall if the gmc grill surround was still on. I suspect latching might be concern. It was a gmc truck though judging from the tailgate and hood.
I should dig up a picture as it had two of my favourite things: old trucks and dinosaurs!
Picture this: completely rust covered 1950 GMC ( with said Chevy grill) sitting at a 4-way intersection corner in a hay field. Grass mid way up the tires, a very large steel cage riding in the truck box carrying...wait for it... A velociraptor!! (Actually a Utahraptor. Jurassic Park made some errors!) I love it!
