When swapping rear axle assemblies, the rule of thumb is:
get the matching shaft with the diff
Contents |
Overview
Automatic and manual cars use different propeller shafts (aka driveshaft or tailshaft). Automatic transmissions are 15mm shorter than a standard transmission, so the auto propeller shaft assembly is 15mm longer. The shaft itself may be the same, but the yoke is longer.
56-series transmissions and 60-series transmissions are the same length, and use the same shaft. It doesn't matter if you get the transmission from a B110, B210 or B310. What matters is which differential you have.
63A 5-speed transmissions use the same input yoke as the Automatics. All you need to support the 63A transmission is the AT prop shaft.
You may need to remove the dust cover (cup on front yoke that fits over end of gearbox) for some swaps. The cup sometimes looks like its purpose is a stopper, to stop the yoke from sliding in too far (see B310 Manual Conversion, tailshaft doesn't match?).
Can you use a B210 driveshaft in a B110? Yes, IF you get the B210 driveshaft for H145 differential (A12, A13 powered B210s). Here are some driveshaft (tailshaft) considerations
- The 56 and 60 transmissions are the same length
- The automatic and standard cars use the same differential, so the back flange is the same
- Automatic and Manual Transmission cars use different shaft assemblies, apparently the shaft's slip yoke is different
- 1974 B210s (and any 12" wheeled A12-powered B210) uses the H145 diff. Other B210 models used the H150 diff which has a larger flange
- Aussie-assembled B210s used a Borg-Warner diff, so that shaft is totally different from any other
Note that all models in a generation use the same shafts -- there is no difference between coupe, sedans or wagons.
The 1971-1973 Datsun 1200 manual tailshaft is the same overall length as the B310 manual but with different flange bolt pattern at rear.
Left: B310 fits to H150 differential. Right: B110 fits to H145
B110 and B310 both use the "Japanese" differential (H145 or H150). So do most B210s, except Aussie-built B210 sedans which use a Borg-Warner differential.

Nissan Part Numbers - Manual
- 37000-H3100 manual, for H145 diff
- 37000-H7200 SHAFT ASSY-PROPELLER manual 4-speed, for H150 diff
- 37000-H7300 manual, 5-speed 63 (NOTE: same as auto)
Automatic Transmission
- 37000-H5100 Automatic, for H145 diff
- 37000-H7300 SHAFT ASSY-PROPELLER automatic, for H150 diff
2-piece Shafts
- 37000-H7500 SHAFT ASSY-PROPELLER (3-joint) 5-speed
- 37000-H7900 SHAFT ASSY-PROPELLER (3-joint) 4-speed
These last two (2-piece shaft, 3-joints) are JDM models with a small 63.5mm diameter shaft. These were used in the L-engine powered cars.
B310 Propeller Shaft Specs
Length
- End-to-end length nearly same as B110 (though diff flange differs)
- ~1245 mm overall from rear flange face to beginning of yoke slip surface
- 1045 mm manual (u-joint to u-joint) <DD I noticed that in my B310 Factory Manual, this is measurement for A/T and 1177mm is for M/T.
- 1177 mm auto (u-joint to u-joint)
- 68.9 mm Tube diameter
- flange: 35mm (from centre u-joint to mating face)

- 37000-H9201 SHAFT ASSY-PROPELLER A14E from 7910-8010 A15E from 8011
These last two "E" models (EGI aka EFI) used a two-piece shaft with center bearing, similar to the longbed GB122 truck.
