I have a stock 1968 Chevy 4X4 with the 327 and 202 heads. I have replacment parts still in the carboard cans. I am wondering what the truck is worth?

I am having issues trying to find out about my grandad's 1968 Chevy 4x4. I know it has the 327 with the 202 2brl stock engine. He bought spare parts for everything on the truck and put them in the camper on the back. I still have them and most are in the cardboard containers you needed a can opener to get to the part. I am talking water pump, altenator, condensor, spark plugs, wires, distributor, and much more. He died several years ago and I got the truck, couldn't bear to part with it for I always thought I would have time to restore it... Three kids later and I don't have the time.  I am wondering what the truck is worth for I have resigned myself to selling the vehicle.
