Yes, almost all the details are the same for the small and big trucks. Most of the differences will be obvious, like you may have a two speed switch, while a small truck may not...
I have a few pictures of my 48 engine compartment and other details that I feel were un molested, as the truck had low miles, and I have seen a number of these trucks by now. Also have worked in a fancy restoration shop, and have a general idea for the way things were done factory.
Another great resource is the service manual, and any other old GM literature. Just flip through looking at all the pictures, and you will see important details, even in unrelated sections of the manual.
Not sure if there is a book for AD trucks, but for some of the other cars I have worked on there were books with collections of articles form magazines and such, those had pictures of the cars when new, and were very helpful for correct restorations.
Grab a pad of post it notes and use them as book marks for details, write on them what detail you see, and then you can compare all the pictures of that one detail and decide what may have been correct for your truck, or what you like best.
If you go to an AACA show, like Hershey PA, they have some very nicely done restorations. It seems the goal for those people is to have correct restorations down to every last nut, bolt, color of wire, and stitching pattern. By talking to some of the owners you can get a feel for how correct their vehicles are, and if they did the work they can help provide details for your truck. Not all of them are correct, but the ones that are will have documentation for every little detail on hand in case the judges challenge anything. Many of the vehicles that are there for the first time will be accompanied by the people who actually did the restoration, again, to answer questions if they arise.
I'll set up a new webshots folder for the 48 2 ton pictures I took. You will have to be the judge of what is correct or not, but it's a start. I may be able to help with some specific questions.
