That certainly is a possibility that he may be able to confirm by simply looking at the date code on the MRF454's.While I do agree with the above statement I always thought the 1200 had the 2290 finals. Since they are crazy expensive now and have been discontinued I would wonder if someone recently rebuilt it with what they could fine. That being the 454 final. If so I sure hope they properly re-worked the amplifier for the 454 finals. They are not a direct swap.

The older amps have numbers on the faceplates. I believe these correspond to their production number for that model, but I could be wrong.Too bad there's no VIN to tell you the model year.
