Saw this add on craigslist. Some things don't look right but I could be wrong. One, what year did that bumped out body line start? I have a '71 and a '75 and neither has it. Two, Isn't that a later dash and dog house? and three the vin sticker looks to nice to be original. Any experts out there think this might be re-vinned? I bought a van from outside of the state and had to get the vin verified by the state police because the dmv wouldn't go by just the sticker. The state police said they verified it with a second vin number stamped on the frame. Anyone know where this second vin is located?
