Something between nothing and a lot.

First off, if it is a "C10" then it is not originally 4WD. You need to check the VIN to see if the truck was originally 4WD or if someone did the conversion themselves.

Also, how tired is that motor, how many miles, etc.

Is that the original color or was the color changed?

The rockers look dry but were they replaced and what rust is on the body in other places?

A few things that _detract_ from value that I see are that the doors have been cut for speakers, which means that the dash has also probably been cut for a radio. Also it looks like the paint is discolored on the driver's door or is that just a shadow?

Sorry but there just isn't enough information (for me at least) to give you a value idea.

Someone from your area can probably tell you what a clean K10 of that vintage would sell for. You can go from there.
