I pulled my ECM out this morning to find that it might be an '87-style ECM. I was just curious what the GM part number was on their ECM in 87 and 85. I only raised this question becaus I figured that my car had an 85 ECM, so I bought an 87 ECM (part # 1227148). The ECM I pulled out of the car was what I think is an 87 (Part # 1226459) Can anyone tell me the part # to an 84-85 ECM and if my suspicions are true? I'm not even sure if this is the right forum....
