What do you think I should ask for it?

Honestly, probably $1500 if you're lucky.

You have to look at the pro's and con's. The pro is that it looks to be in great shape and is a desireable year with the best (IMO) truck grille Dodge had in the 70's.

The con's are the fact that it's a slant 6, 3 on the tree and a long bed. Guy's want V8's, anything other than 3 on the trees and short beds are just worth more. Not knockin your truck at all but I searched for over a year and long beds around here that are put up for over $2500 do not sell. I'd put it at $2500 and see what offers you get.

Then again I can only speak about what I've searched for in CA.
