Want to Buy 67-91 K20-K30

I'm not sure this goes here, but I didn't see a similar spot in the classifieds so here goes. What I want, yes I know some of those years there weren't factory K30's, I would be interested in someone's creation as well as NAPCO and such vehicles. I would like it to be as straight and as rust free as possible, I would prefer manual transmission, but I may consider converting the right truck. I would also prefer single cab in the later trucks, but would consider 3+3 trucks as well. I would prefer little to no lift, I like stock or almost stock trucks. Engine choice doesn't really matter as long as it doesn't need a ton of work, unless the truck is cheap. I'm willing to spend into the $15k range for the right truck and no more than $20k including delivery to me.
Thanks,
Jon
