Go to vintagesleds.com to see many comparables. In Cat for 71, the Puma and EXTs would be on the higher end while others would be more of what ws6 called "common" sleds. If this is common and decent, $400 - $800. They need to be complete cuz when you have to start looking for dash, seats, ect it gets you to more money quickly. If its not decent, buy 2 or more, you will have a parts selection.
