how do i find out what my car is worth.classic truck

Its worth what someones willing to pay. I know theres no blue book on something that old, but it sounds like a peach. do you know someone at a car dealership? or take a dozen donuts to the chevy dealer used car lot and ask what they would price it at, remember you can always come down in price, but if it sell it to the first guy to look at it you'le kick yourself......goo'luck
