The door tag does look legit IMO. Probably a real K, but not a "factory race car". Whether it's a real GT or not does little to affect the value given all the other issues. Absolutely no documentation of what K items are still on the car. Does it still have the original block/engine, heads, transmission, rear end, etc? A lot of "value" is undocumented. K items that it's obviously missing are the intake, carb, distributer, fan, fan spacer, etc. Why would anyone replace the fan with a clutch type fan for racing purposes? This car was previously in a Craigslist ad that was flagged for removal. Both the seller and the high bidder have 0 feedback. I love the statement "No rust on the car". Caveot emptor!
