Nestled deep in upstate New York is a garage packed with rare Ford history, including what might be the single most complete private collection of Boss 429 parts and Mustangs in the country. YouTuber Parker from Backyard Barn Finds paid a visit to Brandon, a Mustang restoration expert who not only hoards vintage hardware but fabricates reproduction parts for these ultra-valuable cars. From new old stock Ford crates to drag-raced originals, this shop is less of a man cave and more of a time capsule.Brandon’s collection centers around the iconic Mustang Boss 429, but it doesn’t stop there. His shelves are stacked with cammer engines, rare factory intakes, and even a twin-Paxton supercharged convertible he built when he was 15. The shop is also home to a Cobra Jet drag car, original Boss 302s, and some one-off prototypes Ford fans only whisper about. As if that wasn’t enough, his father Glenn has a stash of Tigers, Amphicars, Shelbys, and Willys pickups next door. The Boss 429 Lives On In This Mustang Paradise Backyard Barn Finds YouTubeOne of the most remarkable pieces in Brandon’s garage is a 1969 Raven Black Mustang Boss 429, complete with factory shock towers, original KKX spindles, and its matching-number engine preserved in storage. Originally found in New Mexico, the car had just 7,700 miles and had lived most of its life as a drag racer. Despite some minor body damage, it retains a surprising amount of original hardware, including the export brace, oil cooler brackets, battery tray, and more. Even the rear sway bar setup is factory-correct, a rare sight on these already elusive models.Backyard Barn Finds YouTubeBeyond restoration, Brandon actually fabricates hard-to-source Mustang parts himself, including choke cables, spark plug boots, battery cables, and even brake boosters specific to the Boss 429. His in-house production ensures the legacy of these muscle icons doesn’t die out with dwindling NOS supply. Whether it’s the controversial early S-code engines or magnesium valve covers, this Mustang haven has it all. Beyond Bosses, The Mustang Collection Keeps Going Backyard Barn Finds YouTubeThe Mustang focus continues with several other noteworthy cars on the property. Glenn, Brandon’s father, stores a Grabber Orange 1970 Boss 429, a GT500 Shelby, and multiple 1966 Fastbacks, one of which features a K-code high-performance 289. Their Sunbeam Tigers, which Glenn calls the “poor man’s Cobra,” are equally impressive, including a black-on-black Mk2 example awaiting full restoration. There’s even a 1964 Mustang fastback that may predate Ford’s official fastback launch, suggesting it could be a pre-production prototype or dealer-converted mystery car.Backyard Barn Finds YouTubeFrom signs and parts to fully built Mustangs and untouched barn finds, this collection is a living archive of muscle car development. And thanks to Brandon’s operation, this Mustang obsession is doing more than collecting dust. It’s keeping a critical part of American performance history alive, one factory-spec reproduction at a time.
