What Actually Made The 68 Mustang Different
The 1968 Ford Mustang was one of those cars that split a generation in two. Some saw it as a pony car that got too big for its own good. Others saw it as the moment muscle cars became something worth taking seriously. It still shows up at car shows, it still shows up in wrecking yards, and it still shows up on auction sites with mileage that doesn't quite add up. It is not one thing. That is the first thing you need to understand before you do anything with one. Ford redesigned the platform for 1968. Not a full refresh, but enough to change how the car sits and handles. The front end got wider. The frame rails were stiffened. Wheelbase stretched slightly to 108 inches. Ford also split the Mustang into two distinct lines: the standard Mustang and the Mustang II GT package, which was badged as Mustang GT and included the heavier suspension, bigger brakes, and the choice of the 302 Windsor V8 or the 390. This was not just cosmetic. The handling character changed significantly between a base 289 model and a GT or Mach 1. People mix these up constantly when they buy one used. I have spent more time than I care to admit sorting through the variations. One detail most people miss is that the 1968 model year introduced the Bullitt variant, built around the 390 CID V8 with specific heavy-duty components, green paint, and a unique interior. It was not a true high-performance package in the way the Shelby GT350 was, but it carried weight because Steve McQueen drove one in a movie. That matters for value more than it matters for driving. Both things are true at the same time.
The 68 Mustang Car An Iconic American Muscle Machine That Redefined Performance And Style
Understanding what makes this car matter helps if you are looking to buy one, restore one, or just drive one without losing your mind. But knowing what it was does not tell you what happens when you actually try to live with it. That is a different conversation. I will be direct: most 1968 Mustangs you find are already damaged in ways that are expensive to fix. Rust kills these cars faster than engine failure. The floor pans, the inner rockers, the trunk floor, and the rear wheel arches are all weak points. A frame-connector chassis helps, but only if the connectors themselves are not rotted out. I bought one once that looked solid on the surface, drove it home, and found the driver side floor was soft enough to push through with your thumb. That happened because it had sat in a damp garage for twelve years with the windows closed and a roof leak you could not see from the street. Before you worry about horsepower, check the structural integrity. A rust-free 200 horsepower six-cylinder is a better project than a rusted-out 302. Rust affects steering geometry, brake line routing, and suspension mounting points. These are not abstract concerns. I replaced three control arm mounts on a '68 because the welds had corroded from the inside. It cost me about eight hundred dollars in parts and a full weekend. You will see that pattern repeat.
When looking for engines, the 289 Cobra Jet is the most sought after small block from this year. It is also the most faked. There are reproduction heads, incorrect valve covers, and fake casting numbers floating around in enough quantities to make authentication a full-time job. If you are not comfortable decoding casting numbers, bring someone who is. A legitimate CJ 289 has specific part numbers on the block, heads, and intake. Mismatches are common. A block that looks right might be a replacement from 1970 stamped into a 1968 casing. Ford did that during the late model years to save money. It happened again decades later with restoration parts. The 302 appeared in 1968 as a new engine. It was essentially a bored-and-stroked 289 with a different deck height. That means some 289 parts fit the 302, and some do not. Confusion here leads to people buying wrong water pumps, incorrect timing covers, and mismatched exhaust manifolds. Keep a parts book open while you work.

Common Problems You Will Face
One of the more annoying issues specific to the 1968 model is the front suspension bushing setup. Ford used polyurethane-style bushings that were actually rubber compounds, and they degrade differently than modern replacements. When they go hard or collapse, the car wanders on the highway. You will think it is a steering box problem. It is usually the upper control arm bushings. I spent a week troubleshooting vague steering on a friend's '68 before I realized the original bushings had been compressed into flat disks. Replacing them with correctly sized modern equivalents fixed the issue immediately. The car went from vague to precise overnight. That is how subtle these things are. Brakes are another area where people get burned. The 1968 Mustang could be equipped with drum brakes in the rear or disc brakes up front, depending on the option package. Mixing configurations creates imbalance. If you install modern disc brakes on the rear without upgrading the proportioning valve, the rear wheels will lock under hard stopping. I learned this the hard way. A customer wanted better braking on his '68 and put disc rotors on the back with stock drums up front. It was terrifying. The fix involved installing a residual valve and adjusting the master cylinder output. Not difficult, but not obvious either. Electrical issues are routine but predictable. The 1968 wiring harness used a different connector style than earlier or later models. Parts exist, but they are not always plug-and-play. I have seen people splice in 1965 harness sections and wonder why their turn signals behave erratically. The ground distribution scheme changed. Check your grounds before you chase every symptom with a multimeter.
What Actually Makes It Worth Doing
The 1968 Mustang drives like a car from that era. It is not refined. The steering is manual and slow. The transmission throws are long. The ride is firm and communicative in a way that modern cars are not. That is not a defect. It is the point. If you want easy commuting, buy a modern compact. If you want something that demands attention and rewards careful driving, this is a legitimate option. Performance modifications are straightforward if you respect the platform limits. The frame is stiffer than a 1965 or 1966, but it still flexes under hard acceleration. Adding a chassis brace or subframe connectors reduces that flex and improves launch consistency. I installed a set of adjustable subframe connectors on a project car and saw the 0 to 60 time drop by roughly half a second. Not a huge change on paper, but noticeable. The car felt planted instead of squirming. The gearbox situation is worth mentioning. The C4 automatic and the Toploader four-speed manual are both correct transmissions for 1968. The Toploader is stronger and more desirable, but it requires a compatible clutch and bellhousing. The C4 is fine for daily driving but cannot handle more than about 350 pound-feet of torque reliably. If you are building a high-output engine, plan the transmission around that limit, not the other way around.
A Note On Value And Availability
Prices for genuine 1968 Mustangs have risen steadily. A running but rough example can still be found for around five to seven thousand dollars in some markets. A restored GT or Mach 1 in good condition runs twenty-five thousand to fifty thousand depending on originality and documentation. The Bullitt commands a significant premium. Fake or incorrectly modified cars are everywhere, especially online. Authentication requires patience and reference materials. The Marti Report is the most useful tool for verifying a specific VIN. It costs about eighty dollars and tells you exactly what the factory built. Use it before you hand over money. Parts availability is generally good for mechanical components. Body panels vary. Correct reproduction doors, hoods, and quarter panels exist but are expensive and sometimes poorly fit. OEM panels from donor cars are harder to find but often superior. I source mine from salvage yards when possible. It takes longer but the metal is usually closer to specification. If you decide to buy one, go slow. Inspect the structure first. Verify the drivetrain. Then worry about cosmetics. The car will outlast your impatience if you get the foundation right.
