Probably not, at least not without fiddling around with lengths and the attachments to wiper arm spindles.
The end which you had seized, and which on the Holden holds the rubber fitting for the ball joint, is thinner on the Holden arm. I removed the extra plate/shim which is spot welded to the Datsun arm and the boot fitted perfectly. It was only then I discovered the thick 'S' arm attached to the motor was the same fit (including PCD and off-set) on both cars, so I just bolted the entire Datsun assembly, including the 'S' arm, directly to the Holden motor.
Interesting that the two wiper motors were made nearly 35 years apart but had common fittings!
One thing I learnt on my hybrid build was how much car manufactures are really just car assemblers, and how many components are shared across makes and models.
