The gas tank was code dated for a 1988. It also appeared to be the later style.
The instrument pods were all 4 cylinder units, with the exception of the middle one. It's for an 85 GT. (Has the V6 graphics, but the oil pressure gauge in the tach.)
The ECMs were mostly 7170s. Standard issue for the 86-88 V6.
I'll have to look up the associated broadcast codes to figure out which trans they are set up for. (I'll find and post those codes, later.)
At least two of the ECMs were 6869s. Those are from the 85 V6 cars. They were fairly sought after, because the hardware supports the addition of a knock sensor.
If the appropriate PROM chip is left in place, the 85, and the 86-88 ECMs are interchangeable.
