The Hidden Problem: Avanti Parts Scarcity and Fitment Pitfalls
On the surface, Avanti restoration seems straightforward—after all, many mechanical parts were shared with other makes. However, owners and shops quickly discover that:
-
Original and reproduction parts are limited: Many Avanti-specific components, from body trim to dash switches, are out of production or only available as used or reproduction items.
-
Fitment is often uncertain: Even “correct” parts may require modification, as production variances were common, especially in post-Studebaker models.
-
Safety and compliance risks: Non-original or ill-fitting parts can compromise safety, especially in critical systems like brakes, steering, and lighting.
These issues are compounded by a lack of standardized documentation and the evolution of the Avanti platform over decades.
Understanding the Avanti: Generational Changes and Their Impact
To source the right parts, you must understand which Avanti you own. The Avanti lineage is complex:
-
Studebaker Avanti (1962–1963): Original models, most collectible, with unique chassis and parts.
-
Avanti II (1965–1982): Built by Avanti Motor Corporation, GM-based drivetrains, continued use of original body molds.
-
Later Avantis (1983–2006): Varied mechanical underpinnings (Chevrolet, Ford), significant changes in electrical, drivetrain, and safety systems.
Each generation features subtle and not-so-subtle differences in mounting points, wiring, and body structure. Fitment guides like our Avanti Fitment Guide are essential for decoding these differences.
Diagnostic Strategies for Avanti Restoration
Before sourcing or installing parts, a thorough diagnostic is critical. Avanti restoration veterans recommend a structured approach:
Initial Inspection Checklist
- Chassis and Frame: Inspect for rust, cracks, and previous repairs, especially at mounting points.
- Fiberglass Body: Look for stress cracks, delamination, and evidence of past repairs. See Avanti Fiberglass Repair for detailed techniques.
- Drivetrain and Suspension: Identify any non-original components or signs of excessive wear.
- Electrical System: Test all circuits, noting any modifications or deteriorated wiring. The Avanti Electrical Inspection guide offers a step-by-step process.
- Brakes and Steering: Confirm system integrity and compatibility with available parts.
Thorough documentation at this stage prevents costly errors later in the restoration process.
Sourcing Avanti Parts: Real-World Tactics
Avanti parts are not found on every shelf. Here’s how experienced owners and shops approach sourcing:
1. Identify Interchangeable Parts
Many mechanical components—especially in Avanti II and later models—are shared with mainstream GM or Ford vehicles. Researching interchangeability can open up new sourcing avenues. However, always verify fitment against technical documentation or community experience.

2. Vet Aftermarket and Reproduction Providers
Not all reproduction parts are created equal. Seek out suppliers with a track record of quality and compliance with safety standards, such as those outlined by the National Highway Traffic Safety Administration.
3. Leverage the Avanti Community
Online forums, owner clubs, and restoration shop networks are invaluable for sourcing rare trim, switches, or body panels. Many owners maintain private stashes of spares or know of reputable rebuilders.
4. Salvage and Refurbish
For truly rare items, refurbishing original parts may be the only option. This is especially true for dash components, emblems, and unique Avanti body hardware.
Safety and Compliance: Avoiding Critical Mistakes
Safety-critical parts—brakes, steering, suspension, and lighting—must always meet or exceed factory standards. The National Highway Traffic Safety Administration Equipment guidelines provide a baseline for evaluating replacement parts. Key points:
- Brake Components: Only use DOT-compliant parts; avoid unverified overseas reproductions for master cylinders, calipers, or lines.
- Lighting: Replacement lenses and bulbs must meet federal photometric and color standards.
- Steering: Inspect for play or non-factory modifications; use only OEM or certified reproduction components.
Non-compliant parts can jeopardize both vehicle safety and restoration value.
Fiberglass Bodywork: Unique Challenges and Solutions
The Avanti’s fiberglass body is both its signature and its Achilles’ heel. Unlike steel-bodied classics, fiberglass requires specialized repair and prep techniques.
Common Fiberglass Issues
- Stress Cracks: Often found at mounting points or where the body flexes.
- Delamination: Separation of fiberglass layers, especially after impact or poor prior repairs.
- Warping: Resulting from improper curing or exposure to heat.
Repair Best Practices
- Use epoxy-based resins for structural repairs.
- Feather repairs to avoid visible seams.
- Always use compatible primers and paints to prevent chemical reactions.

Electrical System Restoration: Diagnosing and Upgrading
Avanti wiring, especially in earlier models, is notorious for age-related failures and owner modifications. A systematic approach is essential:
Diagnostic Steps
- Visual Inspection: Check for cracked insulation, splices, and evidence of overheating.
- Circuit Testing: Use a multimeter to verify continuity and proper voltage at all endpoints.
- Ground Integrity: Confirm all chassis and body grounds are solid, as fiberglass bodies require dedicated grounding strategies.
Upgrading for Reliability
- Replace brittle harnesses with modern equivalents where possible.
- Use relays for high-draw circuits (headlights, fans) to reduce switch wear.
- Document all changes for future troubleshooting.
The Avanti Electrical Inspection guide offers a comprehensive diagnostic and upgrade checklist.
Mechanical Systems: Engine, Drivetrain, and Suspension
While the Avanti’s mechanicals are often based on mainstream platforms, there are crucial differences:
Engine
- Studebaker Engines: Original Avantis use unique engine mounts and ancillary brackets; correct fitment is essential.
- GM/Ford Engines: Later Avantis may use off-the-shelf drivetrains, but verify accessory compatibility and cooling system fitment.
Drivetrain and Suspension
- Transmission Crossmembers: May require custom fabrication for swaps.
- Bushings and Joints: Use high-quality replacements; avoid “universal” parts unless verified by community experience.
Routine maintenance—fluid changes, regular inspection of wear items, and correct torque specs—is essential for longevity.
Fuel Efficiency and Modernization
Original Avantis were never known for stellar fuel economy, but modern upgrades can help. According to the U.S. Department of Energy, improvements in ignition, carburetion (or fuel injection), and drivetrain efficiency can yield real gains.
Upgrade Options
- Electronic Ignition: Replaces points for more reliable spark and improved efficiency.
- Modern Carburetors or EFI: Smoother operation, better cold starts, and improved emissions.
- Overdrive Transmissions: Reduces cruising RPM for better highway mileage.
