Great looking COE, I too would love too have one like that. It would look great hauling my little Mitsubishi BD-2 dozer.
I am sure you will do fine with your transmission rebuild. I have one that needs both first gears and a rebuild from my 64 sitting on the shop floor now. I will be earmarking all this info for future use. I am no stranger to gearbox rebuilding but never anything with synchros, mostly industrial pump drive boxes.
