This ’69 BOSS 429 Tribute Is A Jon Kaase BOSS Nine Away From Badass!

From the outside, this '69 Mustang Sportsroof looks identical to a 1969 Boss 429. It's only when you take a look under the hood where you'll find it to be on heck of a tribute.

From the outside, this ’69 Mustang Sportsroof looks identical to a 1969 BOSS 429. Popping the hood is a different story, but not with the right engine swapped in its place.

We’ve said it before, and we’ll say it again; in a sea of mostly junk and spam ads, sometimes, you can find a few hidden treasures on Craigslist. In the case of today’s example, we found this completely mint 1969 BOSS 429 Mustang tribute in excellent shape–and it’s selling for pretty darn cheap, too.

The car is a very striking example in this unique color combination, and it turns heads wherever she goes!

We’re trying to contain our excitement here, but if we had the scratch lying around (a mere $27,500), we don’t think we’d hesitate to snatch-up this BOSS 429 tribute. While your author admittedly wasn’t a huge fan of Royal Maroon until now, we probably wouldn’t change a single thing on this Mustang, save for the engine and transmission. But that’s not to say that there’s anything wrong with the original 351W V8 of course–we’d just prefer a Jon Kaase BOSS Nine power-plant–wouldn’t you?

“The car was originally built on July 18th, 1969. There are no signs of any rust, and was reportedly always garaged,” displayed in the original ad. “The car is a very striking example in this unique color combination, and it turns heads wherever she goes! The engine is extremely strong and responsive, with excellent oil pressure and no noticeable oil leaks. It sounds absolutely magnificent, and the automatic transmission shifts smoothly through the gears and the engine temperature always remains cool.”

Royal Maroon was available on more than just a BOSS 429 Mustang in 1969. This Sportsroof model is an original M-code car, and these Mustangs were only available for one year with a four-barrel 351 cubic-inch Windsor V8 option. Whoever buys this car can certainly keep the FMX Select-Shift Cruise-O-Matic automatic transmission, but we'd venture to say a Tremec T56 Magnum XL might be the ticket to happiness if we had things our way.

Detailing the original ad, the new owner of this BOSS tribute Mustang really doesn’t need a whole lot to make this car that much better. It’s already equipped with a 9-inch rear end with 4.10 gears and an Eaton Detroit locker, and the current 351W engine is topped with an Edelbrock four-barrel carb, intake manifold and a timing gear set.

The entire of this BOSS tribute Mustang isn't a bad place to be either. The seats are finished in black vinyl, giving them a look and feel similar to leather, but without the price. It's not a bad setup in our opinion, but we'd probably trade 'em out for something like a set of Mach 1 seats.

Final thoughts on this Mustang tells us that we wouldn’t mind swapping a 5.0-liter Coyote V8 engine into it, pairing it with a Tremec T56 Magnum XL 6-speed manual transmission and a complete independent rear suspension swap either–but that may be a bit ambitious for this particular BOSS tribute Mustang–or would it?
