Just 'cause it's aluminum doesn't mean is doesn't corrode. In fact, most of the body panels will need to be replaced (including all the aluminum ones). The only things that will be saved are the bulkhead (firewall), windshield frame and roof. The rest is gone.

For reasons I won't bore you with, this truck is an elusive candidate for the 617 swap as it is a rare NADA 6cyl version and has a very deep bulkhead. There were only 1500 ever built and all came to the US or Canada. I've got a 616 in my short wheel base truck but thought installing a 617 would be impossible because of the extra length. That is, until I saw this bulkhead!

Anyway, these are bolt-together trucks and almost all the parts are still available so they're very easy to restore. The first big purchase will be a new galvanized chassis.

Anyway, thanks for the help!

And if you haven't seen, this is what the 88" (short wheel base) truck looks like now. Powered by a 616. Even drove it to Labrador last year!
