I'm right on the verge of pulling the trigger on purchasing a 1985 Dolphin. The sticker on on the driver's door panel indicates the chasis cab modification occurred in April of 1985, and it is a National. The only thing that's got me hesitant is during my research it is appearing to me that this model may have been made right at the last possible time it could have been made with the bad axle. Reading on the topic there's so many people jumping in and out it's hard for me to be sure so can someone please take a look at the pic and tell me if enough can be gathered to advise me as to what I would have to do. Thank you
