Rich -
I just went through this exact exercise for my A90 - I literally searched
the world for these shims and even called some poor guy in Switzerland who
had bought a pile of NOS Healey diff parts from a shop in the UK. Of course
he had nothing I could use, and probably thought I was batty.
The upshot of all of my hard work was NO ONE had this stuff, and the best
solution was to modify other shims or make your own. My guess is that shims
used for 6 cyl front bearings might work? If not, there has to be a shop
around that has lots of shims for some reason.
In my case, I just reused the shims I had and, well, it's good enough for
government work.
By the way, I did find these guys, at the very least you could make up a
bunch of the thinnest shims and stack them together to get the spacing you
need:

Actually, they have a little search thing on their website, if you can mic
the shims you have, they might have something in stock very similar.
