Idaho SSP

[aggarcia70]

I Purchased an 88 Coupe SSP from my friend this July. He did not know much about the history of this car, but referred me to the Ebay info and article on Bring a Trailer ad back from Dec 2015 when he bought the car. The original seller listed it as an Oregon Police car, but when working on the headlights last night I saw the buck tags. I pulled them to take pictures. It lists Police DSO Idaho on the second tag and DSO 76-0064. So this would make me think it was an Idaho SSP.

The SSP VIN list on this SSP show Oregon ( no agency confirmation ) with a different DSO number. I confirmed the DSO code of 76-0064 as it matches the code on the VIN tag. Besides a CarFax is there a way to verify what agency actually used the car? How does one find history of their SSP?
