Dumb question but I have to ask.

How do I know what year the rear end is? I have no idea. This truck is pieced together from different years. Is there a mark on the rear end some where are does the numbers I posted give me my answer. It looks like they are all the same for our models. Mine having the load bolt helps. What parts manual do I need to look for?
Thanks for all the info so far.
