You'll find lots of pictures of my 48 2 ton on the link in my signature. Many of the details of how things were put together are the same for trucks big and small. I've seen many AD trucks and have two, the 48 is reasonably un molested (other than missing engine and transmission) Also worked at an antique auto restoration shop and learned a lot during my time there, such as what pictures are helpful later. With that in mind I took lots of detailed pictures of the 48 for reference when I finally get to reassembly, hopefully they help other folks out too.
You will learn a lot by going to shows, junk yards, and asking questions of other AD truck owners. If you see the same detail over and over again likely that is how the truck was put together originally.
If you have specific questions post them, I bet you get answers, and of not answers then opinions.
