Trouble Locating VIN

hello, i just picked up what im sure is a rarity its a 3/4 ton Chevy-Pickup, longbed, i mite be off on the year, but i beleave its a 1951. The reason im posting is im having trouble locating the VIN. any help would be greatly appreciated thakns for your time.

Should be a tag on the door pillar or firewall, did you get any paper work with the truck?

did you get any paper work with the truck?
AND can we see some pics of the truck? :thumbsup:
What are your plans for it?

ill work on getting the pictures, and there was no paper work with it, i tryed the firewall and there was nothing, the door on the other hand had a serial number that i tryed to use as the VIN but was told its a invalid number.

the plans for it are to restore it as a every day driver.

Older vehicles don't have enough digits in the VIN to use carfax and others if thats what you mean by "invalid".
