John M mentioned “long game” in his post. His project has that feel in a much more common (relatively speaking) truck.
Unsolicited free advice: You’re going to have to make some decisions around goals for your project:
1) Keeping the drivetrain absolutely correct - I’d consider this a very, very long game. Unless you stumble across the missing engine parts and they just miraculously work as-is.
2) Keeping drivetrain “sort of” correct - that article suggests GMC was using variants of the Buick six up until at least 1930. This would open up some more possibilities, but still likely take a long time to piece together a working drivetrain.
3) Just get it on the road/ going “modern” - “Modern” in your case might mean a GMC six from the 1940s or 1950s. Would take some adaptation, but you can probably find a running version on FB marketplace in just a few weeks if searching. They are scarce, but they exist.

There are no wrong answers. It’s your truck. Looks like the wood portions of the cab and the chassis are a great starting point, regardless which way you decide to go.
I’ll be following along. Cool project.
