What is my stepside worth?

[P_D]

I used to be a daily lurker on this board, under a different user name that I have now forgotten. I haven't kept up with things for several years, but I still have my truck. I need to sell it, but I don't know what to ask for it. Can y'all give me some advice?

The basics: 2nd owner of a 1972 C-10 shortbed stepside. Straight 6 250 with 3 on the tree.

The good: Body very straight. No rust. New paint in 2004, garaged since then. Blazer tank conversion: gas tank removed from cab and replaced with blazer tank behind rear axle. Filler neck runs thru marker light. Original filler neck hole filled. Interior is good, with a new repro seat cover. Everything works. Reliable.

The okay: Six cylinder and three speed ain't too exciting. It smokes a bit on start up. Spare on the fender- some like that, some don't. Tube grill instead of original grill.

The not-so-good: No bed floor. Hang-down air conditioning not real cold, is super loud and looks pretty rough. Paint scratched just forward of rt front wheel well.

So...what's the old girl worth?
