Dad bought a 46/47...compatiable years and catalogs?

[Puglia10]

My dad just bought a 1947 GMC truck. It looks like 1947 was a weird year since they changed body styles quickly, but it looks like a 1946, not a 1948 if that makes sense. An early 47 if you will.

Does this body style have a specific name to make searching easier? If I search 1947 it gives me the later style, so Ive been searching for 1946. What is different, if anything?

I'm trying to find him some more info and catalogs/parts to start making some changes, just trying to get some info right now since this style is totally new for us.

Wasnt a planned purchase haha, just had to have it! Pics when it arrives, shipping from AZ to MA
