I havent had any luck finding an online source for shop or parts manuals for 1942-1946 GMC trucks... So I am thinking of ordering a printed copy of "Master Parts Book GMC Trucks Models 100 thru 470 (1939-1950) 100-22 thru M470-30 (1951-1954)".
It's pricy, though, at $69, and it goes against my nature to buy big ticket items that are a luxury.
But, it's getting harder and harder to find FLAPS around here or online that can lookup old medium duty trucks. And for a few parts that I've gotten lately, (brake hoses for example) the part numbers for Chevy trucks dont seem to match what's on my truck, exactly.
So my question is, do the 39-47 GMC medium duty trucks have a significant volume of parts that have different part numbers?
This master parts book probably wont be available too much longer, so if this is unique information that the Chevrolet Master Parts catalogs dont have, then I may just get this book while I have a bead on it.
