Here's what looks like a very nicely done K convert that was in the Mecum Monterey auction last month and sold for 37k. i'm surprised it wasn't bid any higher and more surprised that the owner sold it for that price. with what he receives after Mecum takes their commision, i think he could've sold it relatively easily for that price himself.
here's a link to pics of the car-
