    Very nice bezels from Holley website for cheap

    I noticed they are only for the 78-80 models. If they had later models, I'd definitely get one.

    Emissions question

    Emissions question

    Since it is the 8600GVW truck, I read in my info it never had any of that on it. No cats, air pump, or tubes etc. Only thing I removed was the EGR valve and the beat up QJet
