This guide walks you through the types of 1968 Mustang GT for sale builds, realistic timelines, common challenges, and practical tips for managing your project efficiently.
There Are Different Types of 1968 Mustang GT Builds
When building a 1968 Mustang GT, the type of project you choose significantly affects the time, cost, and complexity.
Driver-Level Builds
These are for enthusiasts who want a reliable car for everyday driving. It includes small fixes, performance tweaks, and cosmetic updates. A driver-level build can often be completed in a few weeks.
Restomod Builds
Restomods keep the classic exterior while adding modern engines, brakes, or suspensions. This type takes a few months, but results in a GT that handles and performs better than the original.
Full Restoration
A complete restoration involves stripping the car down and rebuilding it exactly like new. This usually takes 6-12 months, depending on the availability of parts.
Concours-Level Builds
These are ultra-detailed builds aimed at competitions. Every trim, bolt, and paint layer must be perfect. Completion can take over a year.
Stage-by-Stage Timeline: How Long Each Part of the 1968 GT Build Takes
Here’s a detailed timeline that breaks down each central stage of the 1968 Mustang GT build, showing how long every step typically takes and why it plays a critical role in the project.
Disassembly and Initial Assessment
Taking the Mustang apart often takes two to three weeks. Every piece is removed and inspected for hidden rust, worn suspension parts, and missing trim that might affect the rebuild.
Bodywork, Rust Repair, and Metal Fabrication
Rust repair and metal work are the longest stages. Depending on the GT’s condition, bodywork can consume 100 to 200 hours. Proper panel alignment here ensures smooth paint application later.
Engine, Transmission, and Drivetrain Work
Rebuilding the original V8 or installing a modern crate engine takes 80 to 150 hours. Transmission and drivetrain repairs often add weeks but directly affect the performance of the finished GT.
Wiring, Electrical, and Modern Upgrades
Electrical work requires 40 to 60 hours. Installing a new wiring harness, gauges, and modern add-ons like LED headlights is meticulous but essential for reliability and safety.
Paint, Prep, and Finishing Touches
A quality paint job can take one to two months. Stripping, sanding, priming, and curing every coat is slow, but shortcuts here will ruin the Mustang’s final appearance.
Interior Installation and Final Assembly
Reinstalling seats, dashboards, and trim typically takes two to three weeks. Careful alignment and testing during this stage ensure the GT both looks authentic and drives without issues.
Common Time Sinks and Delays You Should Know Before the ’68 GT Build
Even the best-planned 1968 Mustang GT builds hit unexpected roadblocks. You should keep note of the following common delays ahead of time, which helps you set a realistic timeline and budget:
Rust Hotspots and Unexpected Repairs
Rust is the number one hidden delay in restoring a 1968 Mustang GT. Floor pans, frame rails, and wheel wells are common weak spots. Once the car is stripped, new problem areas often appear, requiring extra cutting, welding, and fabrication. A minor patch can turn into weeks of metalwork if structural rust is found. Planning a buffer in your timeline for rust surprises is smart, especially when working on a 1968 Mustang GT Fastback.
Parts Sourcing and Lead Time Challenges
Finding the correct year-specific parts is not always easy. Original trim pieces, emblems, or GT-specific hardware can take months to locate. Even reproduction parts may be backordered, slowing progress. A smart builder starts sourcing early, especially for rare components. According to industry surveys, sourcing vintage Ford Mustang parts can extend a project timeline by three to six months.
Paint Prep and Fitment Delays
Paint is often the longest single stage of the build. Prep work, like sanding, priming, and test-fitting panels, takes much more time than applying the final coat. Poor alignment or panel gaps discovered late can add weeks.
According to a 2014 article on the AACA forums, panel fabrication, body prep, and paint could range from 600 to 1,000 hours or more, depending on the vehicle’s condition and the desired quality of the restoration.
Wiring Complications and Electrical Surprises
Electrical systems in classic Mustangs can be tricky. Old, brittle wiring often needs a complete replacement. Adding modern upgrades such as EFI, sound systems, or A/C increases complexity. Small mistakes during wiring can cause major delays and even require rework. Many restorers recommend setting aside extra days just for wiring and testing before final assembly.
Some Specific 1968 Mustang GT Specific Challenges
While the 1968 Mustang GT is an iconic classic, owning and maintaining one comes with a set of unique challenges that enthusiasts should be aware of, such as:
Unique Trim, Emblems, and Year-Specific Details
One big challenge with restoring a 1968 Mustang GT is finding the original trim and emblems. Small details like GT badges, side scoops, and chrome accents can make or break authenticity. Since these parts were produced in limited runs, many are no longer manufactured. Original Mustang GT emblems in good condition can set you back in excess of $120.
VIN Matching and Engine Number Considerations
Collectors place huge value on VIN-matching parts. The VIN confirms if the car left the factory as a genuine GT and what engine it carried. Without matching numbers, resale value drops sharply. According to Hagerty, cars with matching numbers can command significantly higher prices at auction, sometimes increasing value by 20 to 40 percent compared to non-matching examples. That makes documenting and sourcing the correct parts critical for a high-value restoration.
Common Chassis, Suspension, and Frame Issues
After decades on the road, most ’68 GTs face worn suspension and frame fatigue. Rust in the rear torque boxes and shock towers is especially common. Addressing these issues early avoids safety risks and costly rework later. With proper reinforcement, you can make sure the car handles modern power upgrades while keeping the classic feel intact.
DIY vs. Professional Shops: Which Option is Better?
Deciding between tackling a 1968 Mustang GT build yourself or hiring a professional shop is one of the most important choices for your project. Both options have clear advantages, but understanding the differences can save you time, money, and frustration.
Key Differences in Cost, Time, and Quality
DIY builds save on labor costs, but learning curves and tool requirements can extend timelines. A driver-level refresh may take an amateur 4 to 6 months, while a professional shop can complete the same work in 6 to 8 weeks. Professionals provide high-quality results with access to specialized tools, experienced labor, and reliable parts sourcing. For collectors aiming to ensure authenticity and long-term value, it’s worth reviewing how to spot a real 1967 Shelby GT350 vs. a replica before committing to a build.
DIY projects may save 20 % to 40 % upfront, but mistakes can cost hundreds in repairs. Professional builds are more expensive but reduce the risk of errors and keep your timeline predictable.
Signs a shop will drag the project, and how to avoid them
Some shops take longer than promised, which can stall your project for months. Red flags include unclear timelines, limited communication, and overbooked schedules. Shops that frequently switch staff or subcontract work often delay builds. To avoid these issues, request a detailed schedule with milestones and check references from previous Mustang restorations.
A 2022 survey of independent automotive repair shops revealed that 35.8% of shops anticipated challenges related to parts shortages, which can indirectly affect project timelines
