[MAC67]

hey guys i picked up this truck today for the sole purpose for ebay , wondering what you guys think it would bring , its a 79 chevy k 30 crew 3+3 , 54,695 original one owner miles , all but the last 3000 are documented in notepads , just looked thisafternoon and i removed one of the buildsheets from under the back seat springs and one from under the front seat springs , has the dealership paperwork that list all the options when the truck was special ordered , the previous owner was driving it back from a camping trip in alaska and it burnt a piston , around 39,000 , he had the motor completley tore down and it had a complete rebuild done to it while it was out , tons of reciepts for everything that was ever bought for the truck , it has a 400 small block with a th400 and a 203 , 14 bolt and dana 60 , seems to have 3.73 gears but im not for sure , truck was special order , cab mounts are good but the outer floor supports are gone and the front floor pans near the outer edge need replaced , cab corners have some rot and the front fenders could be replaced , runs smooth as glass , drives like a new one , the bias plys on it are crap , back seat looks to be never sat in , front has rips and duct tape on the driver side , has tilt , cruise , and factory a/c am fm ect , its not by any means to far gone , it has trailer plugs and camper plug ins all over it trailer brake setup and a gooseneck plate , pretty neat all the papers that are with it , i know they dont add much to the value but they are a really cool addition , so what do ya think it could bring ?
