Key Takeaways
- Interchange = two vehicles use the same part. Same Hollander number = same part
- Most vehicles share parts across 3-7 model years within a generation
- Engines and transmissions have the widest interchange ranges (often 5-10 years)
- Body panels and electrical components have narrower ranges (2-4 years typical)
How Vehicle Interchange Works
Every vehicle part has a Hollander interchange number — an industry-standard code that tells salvage yards which parts are identical across different vehicles. When two vehicles share the same Hollander number for a part, that part bolts right in without modification.
This matters because it dramatically expands your options when shopping at a salvage yard. Instead of looking for only your exact year and model, you might have 5-10 compatible donor vehicles to pull from.
Interchange Ranges by Part Type
| Part Category | Typical Interchange Range | What Determines Compatibility |
|---|---|---|
| Engine (long block) | 5-10+ years | Engine code, displacement, emissions standard |
| Transmission | 4-8 years | Gear count, torque rating, bell housing pattern |
| Body panels (doors, fenders) | 2-5 years | Body style generation, trim-specific features |
| Headlights/taillights | 2-4 years | Facelift changes, LED vs halogen |
| Interior (seats, dash) | 3-6 years | Platform generation, trim level |
| Wheels | 5-15+ years | Bolt pattern, offset, center bore |
| Suspension (control arms, struts) | 4-8 years | Platform/architecture, FWD vs AWD |
| Electrical (alternator, starter) | 5-10+ years | Engine family, output rating |
Popular Vehicle Interchange Examples
Ford F-150 (2015-2020)
The 13th generation F-150 (2015-2020) shares most parts across all six model years. The 5.0L Coyote V8, 3.5L EcoBoost, and 2.7L EcoBoost engines interchange within this range. Body panels fit across the generation with minor differences in the 2018+ front fascia. Read our detailed F-150 engine interchange guide for specifics.
Toyota Camry (2018-2024)
The XV70 Camry generation shares engines, transmissions, and most mechanical components across all years. The 2.5L 4-cylinder and 3.5L V6 engines interchange directly. Interior parts vary by trim (LE vs SE vs XLE vs XSE).
Honda Civic (2016-2021)
The 10th generation Civic shares the 1.5L turbo and 2.0L engines across all years. The sedan and coupe have different body panels but share mechanical and electrical components. The hatchback has unique rear panels.
Chevy Silverado / GMC Sierra (2019-2024)
The T1XX platform Silverado and Sierra share nearly all mechanical components. The 5.3L L84 and 6.2L L87 engines interchange across both brands. Body panels differ between Silverado and Sierra above the beltline.
How to Use Interchange Data at the Yard
- Start with your part number — Find the OEM part number on the part you need to replace. It's usually stamped or labeled on the part.
- Look up the Hollander number — Car-Part.com and most salvage yard counters can cross-reference your OEM number to a Hollander interchange number.
- Find compatible donors — The interchange data shows every vehicle that uses that same part. Now you have a shopping list.
- Search inventory — Search our inventory using any of the compatible year/make/model combinations to find available donor vehicles at yards near you.
Common Interchange Mistakes
- Ignoring mid-cycle updates — Manufacturers often change parts in the middle of a generation. A 2016 and 2018 might look identical but have different part numbers for the same component.
- Mixing 2WD and 4WD parts — Transmission, transfer case, and driveline parts are different between 2WD and 4WD versions of the same truck.
- Trim-level electrical — Wiring harnesses and modules often differ between base, mid, and top trims. A heated seat module from an XLE won't work in an LE.
- Emissions equipment — California-spec vehicles have different catalytic converters and sensors than 49-state versions.
