That photo is really handy actually, I couldn't decide if there should be a nut between the alternator bracket and dip stick tube. Obviously not.

To tighten pulley nuts I use an old belt round the pulley and hold spare length of the belt in the vice - you can get a fair amount of torque before it slips. Saves damaging the pulley edges trying to hold it by other means.

I'll give that a go. Not sure how well it will go with no key on the pulley, but there's 2 chances.
:ok

A gentle tap on with a hammer usually suffices to get enough grip. Pillar drills use tapers without keyways for the chucks and they don't move.

Once it’s on, and the alternator belt is tensioned you can give it a final tight against the engine resistance with the van in gear , handbrake on

Dipstick is held by a clip to this tiny bracket.

I'm not 100% the early DG's had the cross brace - ref. '12A', but I'm sure someone here will know.

65 & 90a use a kinked adjuster

no idea why

came across problem when i upgraded from 45a to 90a

Probably the bigger amp pulls harder on the securing bolt so you need to tighten it more which needs longer thread in the alternator.
And Bosch had that shield in stock so VW had to adapt. 
:ok
