60 Series LandCruiser 2H - ARB aftermarket Turbo Rebuild

Can anyone tell me the standard bearing sizes for this turbo.
It is an aftermarket ARB unit fitted possible back in the '80's I understand it is a Garrett T3.

The turbo on Frankenstein the 60 series had seen better days and needs a rebuild. It was beginning to make funny sounds after startup. There is evidence that the compressor wheel was beginning to rub on the housing. If I take the turbo to a professional I get the response, it too old, too risky "Buy a new one" starting price $1,100+

Spare bearing kits are available for less than $100 but are standard sizes. I know that this turbo was rebuilt in 1995 so it could contain non standard size bearings. Does any one know what the standard bearing sizes are?

The housing diameter:
16.81 mm
The shaft diameter:
10.16mm
