[SEE YA]

Hello, looking for a spare for my car, just checking what do the stamped letters and nos mean on the metal plate on the Turbo.

I know one of them is the year it was made?

I have a offer of this one TURBOCHARGER KKK 2729 PORSCHE 930 TURBO 5328 101 5090 I am not sure if its the right one for my 87.

Thanks for any advice.
