1. Identify the basics
Get the exact make, model, trim, engine code, and year of manufacture. VIN is best for precision.
2. Match the part number
Take the original part number (from the part, invoice, or EPC). Compare against the exact MPN.
3. Verify fitment notes
Check specific notes: chassis, options, production dates. If uncertain, ask with VIN + old part number.
Checking compatibility in 3 steps
Make, model, year — the method that stops you ordering the wrong part.
