Whats it worth? Nice 1975 Dodge D100

I can't seem to price these things out online because it's so tough to find them in decent condition. This is a smog exempt 1975 with a rebuilt 318 (few thousand miles on it) with an auto trans. The truck is almost too nice to use as a driver but isn't a trailer queen either. The front and rear bumpers are near perfect. The interior is completely redone and has a tuff wheel. Bed is rhino lined. Body is straight with nice paint. BFG tires, cop wheels and redline dog dishes. Everything on this truck is nice and the guy who built it is a legit mechanic so the odds of anything being pieced together with duct tape and chewing gum is low.

I have an 06 F150 with 67k on it that I'd be willing to sell if I can get this truck for the right price. What do you guys think it's worth?
