The F15A has a single speed (1:1 ratio) Transfer Case, all other 4x4 have a high and low range (1:1 and 1.87:1).
I enquired about the Thornton-Welles locking differential
earlier in relation to F-GTs, now I see the thingy was also fitted to F15As, too. Same part number, C11Q-4299. Any idea which vehicle body types these were fitted to, and are there any vehicles still in existance with one fitted?
PS managed to bring the thread back to Gun Tractors
