Unreal! Bare-Metal 1971 Mustang Convertible Is All Killer, No Filler
Masterpiece in Metal
There really isn’t anything unique about getting screwed on a transaction. It happens to all of us at one point or another. Only the details differ.
In Lyle Vass’ case, the 1971 Mustang convertible that he bought was missing a lot more than he anticipated. Specifically it lacked most of the metal from its quarters, floor, and cowl. “I started cutting, and when I was done only the top, windshield frame, rockers, trunk lid, and rear framerails were left,” he says.
But just because we all get screwed at one point doesn’t mean we deal with it in the same way. Vass has an extensive fabrication background, the consequence of growing up in his dad’s restoration and body shop. “The school bus would drop me off at my dad’s shop,” he says. He also recognized the silver lining that this dark cloud presented: the opportunity to do whatever he wanted.
In no particular order he fabricated a chromoly inner structure to restore much of the strength lost by removing the top of a unit-construction vehicle. Since he basically started from scratch he took the opportunity to raise the front crossmember an inch and fabricate flat floors the same distance higher. And that was just the start. Read on for what he did from front to back.
In 1971 Ford widened the Mustang’s nose, diminishing the car’s aggressive look. To restore it, Vass narrowed and dropped the core support and front of the Mach I hood a scant inch and modified the fenders to match. He also eliminated the seam from the fenders to the chin panel, making the nose assembly a one-piece affair. The nose now comes in from the bottom, so Vass cut off the fender-mounting lips and welded in new ones lower to meet the bottom sides of the inner fender panels.
Naturally Vass had to narrow the bumper, but he took things a step further. He trimmed the backside so the bumper now follows the nose cutline, a job that required filling the gap in the fender. He also thinned the bumper’s cross-section so it barely protrudes from the nose. That, along with eliminating the front license-plate notch, makes the bumper appear more like a body part than a protective component.
The biggest challenge was the thing that made the car unique, its top. “It folds down between the wheelwells and on top of them,” says Vass. He couldn’t just tub the wells to fit wider tires. “I had to widen the car.” He went 2 3/4 inches per side. “I built the quarter-panels, but the wheels looked too far forward without the marker lights.” His solution? “I had to move the rear wheels back 2 inches.” He hid most of the quarter-panels’ increased width by using narrower wheel lips from a 1970 Mach I.
Manufacturing impositions at the time rendered the rear of all Mustangs a mess of gaps and arbitrary cutlines. Vass thinned the bumper as he did with the front and extended the bumper ends upward to meet the fillers. He also extended the quarter-panels below the bumper to align the seams with the trunk sides. That meant fabricating a new tail pan that he extended toward the axle as a belly pan of sorts. Now get this: The roll pan mounts from inside the trunk rather than from under the car. Modified Shelby exhaust tips sprout from that pan and fit in a modified notch in the bumper. The license plate swings down from an electric hinge just ahead of those tips. Acrylic Concepts in Calgary made the taillight lenses. Vass had to make the entire trunk from scratch, and because the tail pan comes in from the trunk he modified the tank to mount higher and from the top. Fabricated inner trunk panels conceal two Air Zenith compressors, their tank, and the battery.
Back up front, Vass smoothed the inner fenders and cowl, shaping the latter for vents and wiper arms. A puzzle of hand-fabricated panels conceals the core support and engine. The car began life as a no-option 302 specimen, but Vass had Deltech in Calgary machine and build a Cleveland. Flat-top pistons and Edelbrock Performer RPM heads give it 11.5:1 static compression ratio. Vass doesn’t know the specs on the roller-tappet cam, but the combo produced 485 lb-ft torque and 550 hp with a 750-cfm Holley on an Edelbrock Air Gap manifold.
A McLeod clutch couples the engine to a World Class T-5 prepped by Astro Performance. Even though Vass mounted the drivetrain 3/4 inch higher than stock, he still had to shave the bellhousing for clearance. The Sanderson FC4 headers that pass the transmission lead to 2 1/2-inch stainless pipes that Vass made from mandrel bends and Flowmaster Super 44 series mufflers. An aluminum Driveshaft Systems driveshaft transfers power to a 4.11:1 cog on an Auburn locking gear carrier. The Ford 9-inch housing is 2 inches narrower to use Mercury Comet shafts.
Vass fabricated a torque-arm suspension similar to an F-body GM to locate the rear axle. A pair of double-adjustable RideTech Shockwaves suspend the car. A Chassis Engineering antiroll bar for a GM Advanced Design pickup induces a little bit of oversteer. The front suspension consists of Chris Alston’s Chassisworks control arms that Vass modified for another pair of RideTech Shockwaves. He also fitted a Baer Brakes bumpsteer elimination kit. Baer also made the 14-inch rotors and four-pot calipers that mount to the front. The rear sports a set of Lincoln Mark V discs. Bolted to those binders are 18x8 and 18x10 Wheel Vintiques Magnum wheels. Vass shaved the sidewalls off a set of P245/40ZR18 and P275/40ZR18 BFGoodrich KDWs.
The interior remains largely stock. Steve Ottens at Old Iron Customs and Upholstery in Strathmore, Alberta, made carpets to fit the flat floor and raised tunnel. The stock seats wear TMI foam and Sport XR covers. Vass kept the dash’s shape but relocated the switches to its underside and replaced the gauge panel with a Scott Drake electroluminescent panel. Visits to swap meets turned up the tilt column and the Forever Sharp half-wrap steering wheel.
We all get a lemon once in a while, but Vass pressed his into one of the sweetest glasses of lemonade. But that’s only the half of it. “This car also started my business,” he tells us. “When friends saw what I was building they began asking me to work on their cars.”
The prospect of a kid on the way and a job that took him away from home for weeks or even months at a time made the decision to go into business for himself easier. “When my son was born I quit my job and started building cars full-time.” In fact, his decision to forego paint kind of testifies to his skills. And the fact that the car remains visually appealing after eight years says something about his eye.
You can find Vass at his Strathmore, Alberta, shop, Rods n Restos. We suggest looking him up if you ever bite off more than you can chew. He has a certain touch when it comes to redeeming lost causes.
