Thought I would join up and read up on first gen trucks. In the market for a truck and have my eyes on an 89 truck. From east central Ohio and don't see many of these trucks around. I don't know many specifics of the 12v engine yet but the rest of these trucks I am pretty good with. I am a Chrysler technician and still deal with the old torqeflites all the time.
