Nick, I am still looking at the conversion options for the rear axle. I
think Heaths housing cut down is looking good for price. The nismo inserts
are oil only, not gas and are adjustable at the top of the shaft centre
with a small screwdriver
Cheers
Feral Errol.

Errol et al.,
I asked a diff workshop about the Commodore diff centre swap;
They said that they hadn't done this particular conversion and that
1.the Commodore axles had 23 splines.
2.The commodore diff would not fit into the Datsun housing.
3.The Stanza axle is weak to start with so it would be better to get a S3
TRX Bluebird conversion, for example.
What is involved in the Commodore axle conversion that you mentioned,
wouldn't you have to get Datsun-pattern (4 bolt) axle-flanges made up?, i.e
effectively new axles.
Looks like the Salisbury axle and 720 LS centre is the 'easiest' way to go
limited slip, followed next by locating a H190 Stanza casing and doing a S3
TRX centre swap (assuming the splines are the same), and finally by doing a
complete rear axle conver$ion.
The works axle that you have looks a beauty, with the 4 pot callipers you
could stop quicker going backwards than you could going forwards!
One thing that I saw on your site that struck me was the adjustable NISMO
strut cartridges.
I am aiming to do a Bluebird strut swap (since I have them lying around) as
a phase 1 then do a skyline/240K swap as a phase 2, with adjustable
platforms and works 'Europe' spec springs and shocks.
Will the NISMO cartridges fit into these struts? Are they gas pressurised?
Are they externally adjustable - without dismantling any suspension etc..
Just a quick note on front suspension, when we talked on the 'phone you
mentioned (from memory) that you relocate the toe-control arms 40mm (out or
in?), I have just had a look at the front end of my car and the stock setup
on the chassis side seems perfect, the transverse arm axis lines up with
the
centre of the toe-control joint, i.e it is effectively a big A-arm member
with no inherent bump-steer. When you take into account the location of the
steering joints, relocating any of the chassis-side joints (singly or two
from three) would be detrimental.
I have re-read the CAMS manual and have come to the happy realisation that
suspension components may be 'interchangeable', so the 10mm longer
transverse arms look like a very good idea.
What are the arm lengths of various Datsun models - are there any swaps
that
would give extra length - with matching toe-control rods presumably.
