No photos, but happy to say it was incredibly close for a base setting (and probably would have been fine) but decreased the backlash 0.04mm and checked and reset the bearing preload to within 0.03mm of target.
Even better settings than the factory untouched open diffs had for comparison.
I hope you're happy with it bud.
Well .... I found this guy who does a good line in LSD

and I thought the addition of said substance (sorry) , err, device would make damp track days a little more rewarding.
Mr TOOL kindly offered to take two hours off from his hectic schedule to fit the LSD and the plan was for me to spanner a few things as well while possibly learning a thing or two. What I fatally did not consider was that TWiR is quite attached to her associated componentry and does not see why a bolt that has been happily doing it's job for 28 years, should be disturbed. And I should have learned my lesson after the suspension bush saga!
It all started off so well. Then one handbrake cable just fell off. Then the little screws that center the brake discs were frozen. Then the backing plate nuts and bolts refused to budge, point blank refused! TOOL resorted to the chisel of death. The worst offender by far though was the right side axle shaft .... not moving, well a few millimeters maybe. And you can't change a diff without removing them

And it was, literally , hours of bashing with Mr BIG Hammer. Hours as in ' two hours was only an estimate sir'. Hours as a measure of my life expectancy because Mr TOOL was not Mr Happy Pants :x
In the end, I think I probably loosened it

as Mr TOOL tagged in for the final round and in the best kiwi tradition, knocked the bastard off. The left side shaft took about four blows from Mr BIG Hammer and out it popped. Go figure
Now, by this time, it was dark which is the greatest time for assembling stuff.

I was fecking about with a few nuts and bolts which were refusing to play nicely, TOOL was assembling the diff and putting things back together before going in search of a squeezy bottle to fill the diff up. All told , I think it amounted to six hours, maybe more! All because TWiR does not do 'change of situation' very well at all.
No time for testing either, I buggered off quite quickly and hoped that Tool's family still recognised him after the 'two hour' job. And when I eventually got home, some of the diff oil had escaped to the underside of the car courtesy of one missing bolt. And the rear brakes were kinda warm and needed attention ... but that's the joy of doing it in the dark, I guess
A massive thanks to Tool though for duty above and beyond.

And apparently, I am no longer allowed to start a conversation with 'would you mind giving me a hand with (insert seemingly straightforward job here) ' ?
I've just finished finding a bolt for the diff and getting the rear brakes playing nicely. Assessment drive coming up over the weekend hopefully.
