Newbie purchased a 1945 CMP

Welcome aboard, John.
Your Chev looks to be a fairly good starting point for a restoration.
It's particularly good to see all of the data plates still intact.
The handbook, parts list and repair manuals can usually be found on eBay. There's also someone on here that sells reprints/CD copies but I'm sorry I can't remember who?!
I can't give you much advice on the missing tipper body, as the Australian versions were locally built and therefore different.
There's lots of people here who can and will help you. Ask away!
Cheers
Howard.
