Thanks for "reviving" this old thread, John. I definitely have something to add.
When this thread was "rolling", it bothered me that no one, including me, had sheet 8105-2 of the 1967 Body Assembly Manual. After this thread finally appeared to "stall", with no definitive resolution, I decided to Post a "Wanted Ad" for the missing sheet. Sometime in late June or early July of 2017, I finally received a response from one of our members that he had an original 1967 Body Assembly Manual that did include page 8105-2, which was dated 07/26/66, and noted that it replaced sheet 8105-2 dated 06/27/66. However, he noted that since the book was 11" x 22", he had no way to scan or copy it. I suggested that he go to Office Depot, or similar place in order to get it scanned. After several days, I received 3 scans, each covering about 1/3 of the whole sheet. I pieced all of the sheets together (which actually came out pretty good), and then scanned the finished product as an 11 x 17. According to the date on the final scan in the Folder on my computer, I have attached a copy of 8105-2, as well as a copy of 8105-3 (which gives part and hardware Part Number information as noted on 8105-2.
I either posted this in some similar subsequent thread, or, more likely, forgot to Post it, which is why I was glad to see it "resurrected".
Interestingly, a coupler of years ago, I came across an earlier version of the 1967 Body Assembly Manual. It, like Osborne's, had no page 8105-2 ; or I should say no page like 8105-2. I say this because in this version (which may be the original first version of the Body Assembly Manual, as the pages are only numbered 1, 2, 3, ... , have only a Section 8xxx at the bottom of the pages, and have no dates other than 1967.
Hope this helps fill in at least some of our questions.
