I believe that those #'s are corresponding with the part #'s. Meaning the few digits on the build sheet are usually the last few numbers of the part number . I'm sure if I'm mistaken I will be reprimanded. Lol
No, those numbers don't seem to have any relation to the part numbers. I posted the part numbers in Post #2. "067" and "072" do not appear in any of the part numbers in the list.
