1988 and 1989 GMC hidden Vin Number location...

[naveedmerchant]

Im trying to get my Texas K5 Blazer truck of 1988 and 1989 registered ... I need to verify the vin number is correct for the truck. I need to match up the door post sticker, Vin windshield plate, and the hidden Vin Number. Does anyone know where the hidden vin location is for both 1988 and 1989 GM P/U is? No one seems to know for sure? Providing there is such a thing?

top lip of frame rail under seat area or just behind seat area .

otherwise its just riveted tag and if you have a sticker on the door.

these old girls didn't get much in the way of hidden vin stuff.
