Joshua,
Glad to see you were able to add some pictures to your post. And even more glad to see
you have connected with the fellas at the Engine Shop.

We do have a big project there. You should be able to get all the help you need in the other places in THE SHOPS AREA.
And keep looking in
the Rocky Mountain Bolters. Some things may pop up there that are closer to you that will encourage your interest in these old trucks -- and meet up with some of the Bolters!
Good details on finding the trucks and neat about the Allis Chalmers tractor that was your grandpa's!!
