The stub axle was originally the whole piece that was held to the axle, or upright by the kingpin. It mounted the backing plate as well as the hub. This was sometimes also refered to as the spindle, & loosely speaking, the terms are interchangeable.
Time marches on & king pins are history. Generally speaking, in a Datsun 1000, the stub axle incorporates the uprights as well as it is all one piece.

The spindle is actually the part of the stub axle that the bearings & seal mounts on & these are dimentionally the same for 1000's, 1200's, & 120Y's up untill May '76 [to the best of my knowledge]
120Y sedans were localy made from that time & many parts of local manufacture were used.

CORRECTION
My 1984 Repco catalogue lists the front wheel bearings, & the grease seal, as being the same for all our small Datsuns from '66 up to November '75, so the chances are, Steve, that you had a hub from a December '75 or later built 120Y.

Meanwhile, back at the spindle, i refered to this because it is possible to use a factory made hub, & non ventilated disc [rotor] on a stock 1000 spindle / stub axle [pick one] if ones brake conversion was to be low cost, easier to do [perhaps] & if the braking performance requirements were not too ambitious.

The hard part is to come up with a caliper that will fit without seriously affecting the steering lock & suspension travel, can be adapted easily to the stub axle, is compatible with the disc rotor in thickness & diameter, & has a piston diameter that is very close to the 48.1mm diameter of the 1200 & early 120Y brake caliper.
Oh yeah, they need to be reasonably cheap & readily available too.

Unfortunately, the caliper from the aforementioned Datsuns is bulky & not really a suitable candidate for this conversion, & the caliper from the later 120Y is a little beaut, but has a seriously smaller piston diameter. Bummer.
Does anyone have any ideas?

Spindle? Stub?
You say potayto, i say potarto,.. etc...
