Whats it worth '72swb body??

['68 K-10]

I found someone interested in selling a 72 swb complete body no engine or frame or anything just the body with all the guts dash, controls, column.... it has been painted and he claims is in very excellent condition, no rust. the hood is a fiberglass cowl, but is one of the first so it is a little wavy. the dash has new guages in a custom aluminum cluster. no seat or carpet. he just said do some research, to see how much its worth so what do you all think? i know i need pics but i won't have those for awhile. i have a longbed and want to keep mine that way.
