This article primarly compares RWD Sunny propeller shafts. Note that 1200 Coupe, Wagon and Sedan use the same shaft, but the 1200 pickup uses a different length.

Swap Considerations

When swapping rear axle assemblies, the rule of thumb is:

Get the matching shaft with the diff

In general, all B110, B210 and B310 and B120 driveshafts are the same (or close to same) overall length, but the ends differ:

* Auto vs. Manual 
* Japan diff vs Borg Warner diff 
* H145 vs H150 vs H165 diff 

Shafts for all 3-, 4- and 5-speed 56-series and 60-series boxes are the same and only differ for the type of diff fitted.

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.

Large Diameter or small-diameter Slip-Yoke? Depends on transmission.

  • 56- and 60-series gearboxes use ~27mm yoke Outside Diameter
  • 63-series and Automatic use ~35 mm Outside Diameter yoke

Both are same diameter. Some use a dust shield

These last two "E" models (EGI aka EFI) used a two-piece shaft with center bearing, similar to the longbed GB122 truck.

B210 vs B310 Auto Shafts

Overall length (from end of slip-yoke to diff flange)

  • B110 auto shaft:
  • B210 auto shaft: 1345 mm (53-1/8")
  • B310 auto shaft: 1208 mm (47-3/4" ).

B210 Swap Notes

The 120Y Borg Warner tailshaft has 1 inch u-joints. The BW shaft can be modified to fit the H150 by changing the rear flange to a Series 1 Bluebird one-piece tailshaft. They have the same size uni's & the rear flange fits a H165 diff, so it'll fit the H150. Just:

  • swap the rear flange onto the 120Y tailshaft, along with some new uni's.

Or

  • get the Bluebird tailshaft cut down to length & the A-series front yoke fitted

A10 specs

  • A10 with L20B engine
    • overall length: ~1375 mm
    • ~1245 mm overall from rear flange face to beginning of yoke slip surface

P510 (1600) sedan (2 or 4 door?) Propeller Shaft Specs

  • 1082mm (u-joint to u-joint)
  • 63.5 mm Tube OD, 60.3 ID
  • Same bolt spacing for diff flange as H165
  • Diff flange locating spigot different diameter (smaller) to H165

610 (180B) Propeller Shaft Specs

  • End-to-end length 1183.5
  • 1000 mm (u-joint to u-joint)
  • 148.5 (end of yoke to centre of u-joint)
  • 63.5 mm Tube diameter
  • flange: 35mm (from centre u-joint to mating face)
  • Tailshaft for Hardtop and Wagon are 2peice and I havent bothered entering this information.
