Is driveshaft length same for different manual transmissions?

Car was originally /6 with manual 3 speed (think it's known as A230). A833 4 speed OD installed using same drive shaft which I did not expect. I suspect, if A833 4 speed is installed, drive shaft should work. Differential is the original 7 1/4. This will be a temporary install until 8 3/4 is installed. To sum it all up. The A230, A833OD and A833 are all the same length and accept the same yolk. Is this correct?
