Ford’s factories had to be running night and day in 1965-66 to keep up with demand for their new Mustang. 1966 would be the high-water mark, when 607,568 of the cars were built, with 35,698 being fastbacks like the seller’s machine. This car is said to have once had the 225 hp 289 V8 under the hood, but that engine is long gone. So, it’s a rolling project that may have a rust-free body for the buyer to work with. Located in Wichita, Kansas, one bidder has clicked the button for $10,000, but the reserve is unmet here on eBay.

The fastback didn’t arrive in the Mustang’s first partial year of production (sometimes called 1964 ½). Beginning in 1965, it would serve as the foundation for the Shelby Mustangs that would follow. This ’66 edition is finished in Wimbledon White, which the seller is said to be both its original color and finish. The car is in a state of partial disassembly, but we’re told all the parts are there to restore the automobile. The seller says there is no rust present and none of the sheet metal has ever been replaced, so it should work as a solid base to go from. The engine compartment looks to have been repainted already.

The black interior largely looks good, and we’re told the factory headliner is in great shape. The principal miss on the car is that’s its original A-code V8 is missing as well as the original 4-speed, but the seller says he has a rebuilt transloader that will go with the deal. Restoring this car was always a dream of his, but life has its ups and downs, and a recent down is forcing him to let it go. It was a Rally-Pac car from new, meaning it came with an optional tachometer and clock fitted on the steering column. It looks to still be there.

One of these fastbacks in primo condition can fetch north of $50,000. If you can replicate the original powerplant, get it all painted, and put back together, you could have a solid car here to show off. But it’s not the truly collectible K-Code version of the Mustang whose 289 V8 was tweaked to put out 271 hp.
