The Bentley gives spec for the thickness of the spacer as the thickness was increased over the production run.
I can't find any specs in Bentley for the spacer length.
Some quick measurements from parts in my stash
Inner bearing inner race thickness = 17 mm ( that's the nominal thickness, I miked brand new bearing race at 16.95 mm)
Inner race, outer bearing thickness = 19 mm ( I miked brand new as 18.93 mm)
Spacer, one of my used spacers measures 42.80 mm
Add that up, 78.8 mm
On a used stub axle and hub, when hub installed on axle, but not pressed down by nut, just pressed on by hand, space between the surfaces that the inner bearing and the outer bearing lie against measures 76.1 mm.
To be clear, the hub is pushed down until it fetches up on the end of the splines.
So you have, nominally, 2.7 mm of room before the hub bottoms out on the end of the splines on the stub axle.
