Problem is that you have the Sand Crawler backwards at the Lars homestead. We can clearly see that it is the same side we saw earlier.
Also, your comment about the SE Sand Crawler shot is confusing. That was filmed for the 97 SE. You seem to be implying that it was filmed in 1977 and that photo clearly is not how Peterson looked in 1977. I may have just misunderstood what you were intending to say here.
