    Had my body media blasted - was wondering where the hidden VIN's are located ? Found the VIN on the frame. Are there others on the body ? Also, my Protecto Plate gives my rear axle code as ON. Cannot find this code on the passenger side axle tube.

    On axle tube passenger side facing the front of the car. Stampings can be "light".

    ON = 3.64 1968-70 Buick only 8.2 gear set version. You can look at the gears and tell what is in there now.

    BTW, had to use laquer thinner to remove all the crud on axle to see the codes.

    It's faint but you can see it.

    The hidden VIN should be on the engine side of the firewall behind the heater or A/C box

    I have found that certain plants did things differently. Some stamped frames,some stamped the body,some did both,some did none.

    My all original panel/body/frame, absolute rust free Reynolds car had no hidden vin stampings anywhere that I could find when I restored it. Had every nut and bolt off the car and needless to say every piece of metal.

    69-70 axle tube stamping can be on the drivers side. I had a 70 ON and that is where it was. I had a perfect 70 OO code and no code whatsoever .

    Jason, I never found one there on a Flint built car at least 70-71. Only GMAD built.

    Ive noticed them on a few cars Ive parted out over the years, but they must of all been Framingham cars which are common around here. I mistakenly assumed they all had it stamped there

    Jason I got your back.... I have never seen one on a Fremont or Flint build and I've seen many.
    But I have seen one on a car behind the A/C box too. 1970 GS 455 Kansas built

    I know there was a fake GSX for sale out there that had a VIN there. And no it did not match VIN on dash. Some guys that fake things should be jailed for stupidity alone,
