Rover P6 - 1970 Series 1 V8 - Planetary Gear Shims for Rear Differential Diameters?

Does anyone have the internal and external diameters of the planetary gear shims that help adjust diff lash in the very heart of a P6B diff? My diff has some serious lash in it after 113,000 miles (181,000 kms) and its starting to become a bit of a chore to drive.
I had the diff apart last night but didn't take note of the shim measurements. I'll play around with different thicknesses in time once I have the specs correct.
Any information would be appreciated.

I'm not sure of the diameters but i do have a box of diff shims and the adjusting dolly and spacer. If you have some idea what thickness your after i can have alook and see if I have them. which Edinburgh are you in?

I wonder what has happened to your diff Fraser, to have such play at such a low mileage? My diff has over 360,000 miles ( 580,000km), and it is running beautifully, giving an indication of their longevity.
