I don't know the answers to your questions, but...
There was a guy in my 4x4 club that has a 60s era f-750 4x4 that had the manual tranny, I assume it's like you're talking about, mounted behind an automatic tranny.
I think the club has a website. www.ozarkmountain4x4club.com there maybe some pictures, or at least you can message them and ask about the truck.

Those old twin stick Macks are a whole 'nother animal. The second stick is a range selector. (now-a-days it's an air operated toggle on the shifter.) It was the old Mack straight cut tooth five speed. You shift one through five in low range, then you shift up to high range and shift back to first gear. (which requires two hands to do this. Which hand do you leave on the steering wheel?) By the way, the transmissions are NOT synchronized.
Mack's are finicky trucks, if it didn't like how you put it in gear, it would throw it back at you and try to break your wrist in the process. The plus side is, you could do NOTHING to hurt that trans. I think it was literally bullet proof.
