This is an ok manual. It is much better for the passenger cars than the truck. It does have some good information about transmissions and the drive shaft.

I don't have this rare book. I believe it has much better info and pictures of truck equipment. It was meant for the Chevrolet salesmen to help with selling the truck. Last one I saw for sale was $75.00

My copy is a bit ratty, but still ahs good info you would expect like fluid amounts, spark plugs, maintenance intervals

I got this from a guy in Australia. It covers the really big trucks from 1940.

This is a very neat book. I t has a artist drawing and line drawing of every truck platform for 1940, including the bus, flatbeds, COE, rack trucks, etc.  I've included a few more pages from this one so you can see what I'm talking about.

Like the shop manual, it is really best for information on the car models

I don't own any of these signs. I just like this kind of stuff.
