I was noticing that as well Marshall. I think you are correct. Whatever it is, it's not a Wagoneer hood.
At first glance I thought that Bronco was a Bronco II. It wasn't until I looked again that I realized it was a 92-97 Fullsize Bronco. Gives even more scale to the Chrysler wagon in front of it.
You guys definitely have an eye for detail! I was on board with the Jeep hood as well.... OK, what about the pickup?
Looks like maybe a '72-ish Dodge P/U off to the left and behind the Chrysler wagon. The really old one off to the right? Maybe a Dodge as well, like a '46 or so..... this is just a guess though.
I was looking at the pickup to the right. I agree that it looks Dodge-ish. It's not a spit window and it's a flat windshield.
I would probably guess a 1926-‘27 Model T Racer. Just a guess. the grill looks Ford. In reading many racers customized the exhaust placement. Just a SWAG.
