Found a 70 C-30 what's it worth?

[Ozark Tim]

I found a 70 C-30 single rear wheel truck with a utility box on it. Utility box is shot, cab has rocker and floor rust.
307 was replaced by a local Chevy dealer in the 80's with a Goodwrench 350 (a blue one) and all the original 307 parts were transferred to it so it is not a botch job.
This truck has the eaton HO52 or 72 with leafs and is a 4-spd.
Paint is crap and the truck is a plain light optioned work cab.
Worth much?
Thanks for your input and sorry no pics!
