My 1968 Golden Anniversary stepside shortbed?

[71HUGGER396]

I hate to do it but do to a rare disease (Huntington's), I may have to sell all my truck. This will be the last thing I sale, I hope. But I'm going to Truck Carlisle to sell my garage full of parts and maybe my Blazer if I get it back in time. Since I am driving Goldie up there, if some one would offer me money, what price would you not turn down. It had the drive-train replaced with a 350 instead of the 307 that was in it. She is all original paint with very few dents. it goes down the road like a brand new truck. I added a 3/5 spring drop, factory tilt column, buddy buckets, and a used sport white rear bumper.
What's a good price?
