Aside from the Shelby variants, this Mustang could have one of the most desirable spec sheets around – ’66 fastback body, K-code engine, and 4-speed toploader transmission. It doesn’t get much better than this! The “K” in the VIN proves that this car came from the factory with the high performance version of Ford’s 289 V8. It didnt come from the factory with the scoops or white paint though so those may have to go. Then again, the the engine does run so I’d be tempted to just fix the floors, replace that hideous velvet interior, and go through the mechanicals. Then I’d be able to enjoy the car sooner and not risk the possibility of not getting it back together after tearing it all apart. There is something enduring about a beater Mustang.
