Stock turbo specs

I havent been able to find anywhere what size (prefferably in mm, not in relation to others) are the compressor and turbine wheels in the stock 86-87 turbos?

Thanks

No one has any idea?

The compressor was a T04B, 2.75" back disk and ~ a 1.95" inducer. It was in between the S-3 and T5/6 compressor. I think the turbine was 1.898"/2.319".
