56 4spd on the left, and 63a 5spd on the right.
The 56's are okay for what they were orignally intended to do I guess. You can still see the remains of the bearing race on the 56 countershaft. That bearing collapsed in that particular gearbox. (It had been howling like a banshee for some months) I aquired that gearbox for parts for a dozen Speights. And used some of it's gizzards to fix another 56.
