Thanks guys you have confirmed exactly what I was thinking. Regarding the taper roller bearings they sit on top of these shims as follows and are sided as follows:
LH: 99905906400 is a 50x90 (20x large rollers)
RH: 99905906602 is a 50x80 (smaller rollers and more of; around 25)
These were fitted correctly.
Now I've just checked the other side and the shim on that side appear to be much thinner, around 1mm:
However on the previously fitted diff the markings kind of indicate a much thicker shim was in use before.
So going forward I need to speak to the guys who fitted the diff again and try and establish exactly what they did. I then also need the procedure for how you do the installation set-up for a new diff.
The LSD housings are slightly different in places however the critical mounting surfaces for things like these shims bearings all appear to be the same as the OEM LSD, so my thinking is the previously fitted shims should be just about right for this new LSD give or take a few 0.05mm.
The main issue I really have is nobody really gets involved with this type of work. All OPC's would most likely outsource gearbox work, the likes of Manthey the same. The only company I know and trust with this are 'Sport and Classic' (Mike) but they are in the UK. I have lost pretty much the whole driving season last year due to this, so this winter I need it resolved so that I can crack on and get this finished.
