vin help 79 lwb

[glhman222]

i recently acquired a 79 chevy c10 longbed

i cannot find the vin on the truck anywhere, i have a vin on the title but there's no vin i can find on the truck, not the doorjambs, not the dash, and theres no rpo sticker

if indeed the vins are gone from this vehicle can i get my money back from the guy legally?

i need to find the vin on this truck

thank you
