Agree with LRS above,
when a car is engineered by an approved person, the report would have been sent to DOT/TMR and archived, as you would imagine pics werent readily available, but might have them on file,
So if in the instance you were ordered to TMR, records will show what was in/on the car at that time, of course we upgrade/update our cars, and would have to ensure those seats are ADR compliant,
If in doubt in the end, get new seats perhaps
