[4x4k30]

I have a 77 k3500 it has the vin plate on the door jam and one on the drivers door there is a sticker and it has the vin on a sticker in the glovebox when I took off the bed to paint the frame I could see the vin stamped on top of the right side frame but it was just the last 6 numbers of the vin. and I have not seen the vin anywhere else so I think that is the only places to find the vin.
