I’m selling OE parts in the automotive category, and I’m running into a lot of return issues. Most of them are “doesn’t fit” or “doesn’t work.” The photos I use don’t match what the customer’s original part looks like.
I’m trying to find a tool that can help with:
OE → correct image: What does this OE number actually look like? (real photos or diagrams)
OE → all compatible vehicles: Show me every make, model, year, engine, and configuration this part fits.
Vehicle / VIN → OE number: If someone enters their vehicle or VIN, what’s the correct OE number for, say, a fuel injector?
Does any tool out there cover one or more of these? Paid is fine.
Also open to advice on how to reduce these “doesn’t fit” returns. The issue seems to be that customers either:
Buy the wrong part because our OE image doesn’t match their original part
Or they don’t know their OE number and just search by vehicle + part name
Any help would be appreciated.

Don’t forget the big OEM suppliers themselves — Bosch, Denso, Federal-Mogul, TRW, Valeo. Many of them have public or dealer-facing catalogs where you can search by OE number and see original reference images.
If you’re sourcing from a factory, they should provide you with the official fitment data. That’s your starting point. If they can’t, that’s a red flag.
eBay actually has built-in tools for this category. In Seller Hub under “Motors,” there’s a tool called VioFitment. You can upload your OE numbers and vehicle compatibility lists directly. It also helps with listing accuracy.
myFitment is another external tool that integrates with eBay. You can bulk-upload OE numbers and it generates the full vehicle compatibility list. It also supports reverse lookups — enter a vehicle or VIN and it shows you which OE parts fit.
These tools help prevent the exact issue you’re describing: customers buying the wrong part because the compatibility data wasn’t clear.
RockAuto is a great free resource. Search by OE number and you’ll often get multiple angle photos and vehicle fitment details. AutoZone and NAPA have similar search functions.
For manufacturer-specific OE lookups, some OEMs publish their own catalogs. For example, GM’s official parts site lets you search by OE number to see which models it fits.
If you have a VIN, you can sometimes reverse-lookup the OE number on those same retailer sites. Not always perfect, but a good starting point.
TecDoc is the most comprehensive automotive parts database. It covers a massive range of vehicles and parts across Europe and North America. You can subscribe for access.
OE → images: Enter the OE number, go to “Illustration,” and you’ll get high-res exploded diagrams and realistic renderings.
OE → compatible vehicles: It will show you the full list of makes, models, years, engines, and configurations. You can even export it.
If you’re serious about accuracy, TecDoc is worth the subscription.
