Which transmissions bolt into the 1200, and what is involved in swapping them? Basically any B110, B210 or B310 gearbox will bolt to any Nissan A Engine, but minor fabrication is needed in some cases. In no case will a custom driveshaft be needed - if you can source the appropriate factory shaft.

Overview
Interchange
Only these interchange, meaning they can be bolted in place and used as-is with each other no matter which car they came from:
* four-speeds for A14/A15 engines * four-speeds for A12/A13/A12A engines
Emissions
Note that this simple interchange list does not include emission control interchange. Some year/model/market transmissions include a Neutral Switch or Top Switch - and some include both.
RHD vs LHD
Right-hand drive vehicles have transmissions that differ from Left-hand drive. See
Exception: the B210.A14 five-speed is same RHD and LHD.
To swap the others RHD to LHD, you will need:
* Clutch Release Lever * To use LHD gearbox in RHD car, cut out the lever hole * To use RHD gearbox in LHD car, Drill and tap the slave boss
Swapping
There are several minor differences between most transmissions that prevent a strict interchange, although they can all be swapped with some additional parts sourcing or minor fabrication. Differences include:
* gearbox mount location * reverse lamp location * transmission length and output spline * torque rating. The 56 is not recommended behind A14/A15
Strength
Gearboxes are rated for maximum torque (twisting force). The HP is irrelevant unless engine capacity or RPM are known, from which the torque can be deduced.
* 60-Series Transmission add lightness for best performance suitable for the torque of an A12 or A13 engine
* 60-Series Transmission are stronger, but heavier suitable for the torque of an A14 or A15
* 63-Series Transmission are larger and very heavy Fitted to five-speed B210 with A14 engine suitable for supercharged A-series engines
The 63 5-speed gearbox was designed for the 1.6/1.8/2.0 liter class, but used in the B210 because a lighter 5-speed was not available in 1976.
Sources
B110
* 3W56R - three-speed column shift * F4W56L - early 1200s * F4W56A - lates 1200s * FS5C56A - Datsun 1200 GX-5
B210
A12-powered * F4W56A - B210 with A12 engine * FS5C56A - B210 with A12 engine, five-speed
A14-powered * F4W60 - 60-Series Transmission, four-speed * FS5W63A - 63-Series Transmission, five-speed
B310
B310 (markedted as Datsun Sunny, 210 or 140Y/150Y) used these gearboxes:
A12/A12A/A13-powered: 56-Series Transmission * F4W56A
A14/A15-powered: 60-Series Transmission * F4W60 - four-speed * FS5W60L - five-speed dogleg shifter (1977-1979) * FS5W60A - five-speed standard shifter (1980-1982)
Swap Notes
4-speeds - F4W60 fitted to A14/A15 - F4W56A fitted to A12A The mount points for the crossmember differ
5-speeds - FS5W63A fitted to B210 - FS5W60 fitted to B310 The mount points for the crossmember differ The output spline and length differs
60-series are same length both 4-speed and 5-speed. The output splines are same. Ditto for the lighter 56-series 4-speed. You need to fabricate a mount adapter to swap these in a B210. B310 came with 3 different crossmembers which will bolt to any B310 so factory parts can be used.
