Hello from Mississippi. Good ideal from will e. Start with pictures of the boxes. Then work your way up to the "What the heck are these" pictures. Then one day you'll be able to post the "Completed" pictures of your new family member! Welcome to the club.
Welcome from North Carolina. Hey buying one in the boxes saves you time of tearing down and you can see everything. It is probably worth more unless you fear the puzzle of putting back together. It is not a huge task just do small steps and ask lots of questions.
The last box car I bought had ram air, 351 C 4-V CJ vert with tons of NOS and extra parts.
