Signs of Quality in 1968 GTO Parts
When shopping for 1968 GTO parts, quality is of paramount importance whether you’re undertaking a full restoration or refreshing key systems for reliability. Here are some key indicators of high-quality components:
1. Material Authenticity and Finish
- Sheet Metal Parts should have crisp lines, proper thickness, and the correct stampings. Look for EDP-coating or rust-preventative finishes on reproduction panels.
- Trim and Emblems: Quality reproductions use die-cast, triple-plated chrome or stainless that resists flaking and pitting.
- Interior Parts: Dash pads and panels should use UV-resistant vinyl matching original grain and color. Shifter bezels should fit snugly and not warp under heat.
- Hardware: Look for factory-head markings, correct black oxide or zinc plating on bolts, and molded-in part numbers when possible.
2. Precision Fit and Compatibility
- Original Fit: High-quality parts drop into place with minimal adjustment or modification. Repro quarters, doors, or fenders should align with factory dimensions.
- Mechanical Parts: Starters, alternators, or engines should come with specific fitment notes to match GTO’s engine codes and transmission types.
- Electrical: Wiring harnesses should feature original-style connectors, wire color codes, and harness clips.
3. Reputation and Warranty
- Established Brands: Trust parts suppliers known for classic GM/Pontiac expertise.
- Warranty: Look for at least a 1-year warranty on moving/mechanical parts. For reproduction sheet metal, some manufacturers offer fit-and-finish guarantees.
Customization Options for 1968 GTO Parts
The 1968 GTO is a canvas for originality, performance, and personal style. Whether you’re preserving a factory look or enhancing for modern performance, these are popular areas for customization:
1. Performance Upgrades
- Engine Components: Swap stock iron manifolds for lightweight aluminum intakes or performance cylinder heads for more horsepower.
- Brakes: Upgrade to front and rear disc brake conversions for improved stopping power—often available as bolt-on kits.
- Suspension: Adjustable coilover shocks or stiffer sway bars transform ride and handling for street or track use.
2. Modern Comforts and Safety
- Electrical/Lighting: LED interior and exterior bulb conversions improve visibility with lower power draw. Modern wiring harnesses increase reliability.
- Audio Systems: Direct-fit speaker setups allow you to maintain the stock look while enjoying digital audio.
- Air Conditioning: Retrofit systems provide hidden climate control using original dash outlets.
3. Visual & Interior Modifications
- Exterior: Reproduction Judge stripes, hood scoops, or period-correct aftermarket wheels elevate curb appeal.
- Interior: Custom upholstery, from factory-correct houndstooth to modern leathers, can blend heritage with comfort.
Durability: How to Choose Parts That Last
Investing in durable parts means fewer repairs and more time enjoying your GTO. Consider the following:
1. OEM vs. Aftermarket
- OEM (Original Equipment Manufacturer): These parts match the original specifications for fit, finish, and longevity. They’re often costlier but provide peace of mind.
- Reproduction Parts: Quality varies; look for trusted brands and user reviews. Some high-end repros match or even exceed OEM durability, especially in sheet metal or trim.
- Used/Salvage Parts: Genuine, but age and storage matter. Inspect for rust, cracks, pitting, and fatigue before purchase.
2. Coatings and Treatments
- Sheet Metal: EDP (Electro Deposit Primer) or powder-coating increases rust resistance.
- Hardware: Stainless or zinc-plated bolts resist corrosion better than raw steel.
- Suspension & Steering: Polyurethane bushings last longer and resist deformation more than original rubber.
3. Environmental Resistance
- Select parts with UV protection or weatherproofing for exterior and trim pieces to prevent sun fade and cracking.
Practical Tips and Best Practices
Restoring or maintaining a 1968 GTO can be overwhelming, but these tips help ensure a smooth project and lasting results:
- Always Verify Part Numbers: Use your VIN, trim tag, or assembly manual to confirm compatibility. GTOs often share parts with LeMans or Tempest but not always.
- Inspect Used/Salvage Parts Closely: Look for rust-through, hidden repairs, and compatibility. Many sellers provide close-up photos or will answer questions on request.
- Buy In Sets When Possible: For brakes, suspension, or hardware, matching sets ensure even wear and easier installation.
- Test-Fit Before Painting or Installing: Especially with sheet metal, do a dry run. Some trimming or drilling may be needed for vintage reproductions.
- Keep Receipts and Warranty Information: Many classic parts sellers honor returns/exchanges only with original receipts and intact packaging.
- Document Your Build: Keep a notebook or digital file with part sources, part numbers, and installation notes. This helps for future repairs or resale.
- Ask for Installation Instructions or Diagrams: Good suppliers will include or email diagrams—essential for wiring or complex assemblies.
- Consider Long-Term Support: Choose suppliers who update inventory frequently and stock hard-to-find items like early production variations or rare trim.

FAQ
- What are the most common 1968 GTO parts needed for restoration?
Typical needs include sheet metal panels (doors, fenders, trunk lids), bumpers, grilles, interior trim, emblems, engine dress-up items, brakes, and weatherstripping due to age-related wear or rust.
- Are 1968 GTO reproduction parts as good as OEM?
Quality reproduction parts from reputable manufacturers can match or even surpass original GM parts in terms of material and fit. However, fit and finish may need slight adjustment. Always read recent customer reviews or ask for fitment guarantees.
- How do I verify that a part fits my 1968 GTO and not another A-body model?
Use your vehicle’s VIN, body tag, and consult original factory assembly manuals. Some GTO parts are shared with LeMans/Tempest, but many are unique. Confirm part numbers and specifications before purchasing.
- What should I look for in used or salvage parts for a 1968 GTO?
Check for rust (especially at seams and lips), previous repairs, hidden damage, pitting on chrome, and overall straightness of the part. Request detailed photos and description from the seller before committing.

- How do I protect new sheet metal or trim parts from rust and damage?
Prime, paint, and undercoat panels as soon as possible. Store in a dry environment, and apply wax or sealant to chrome. Use rust inhibitors or anti-corrosion sprays inside boxed sections and seams.
- Do wiring harnesses come complete with connectors for 1968 GTO?
Quality reproduction harnesses often include factory-correct connectors, clips, and color-coding. You may need to specify options for options like power windows, air conditioning, or special lighting.
