I usually go to dealer parts websites to find OEM part numbers. They have diagrams for the majority of the vehicle.

rockauto has an extensive parts catalog. Be mindful you don’t just get the cheapest thing, cause they do sell from a variety of manufacturers, and cheap parts tend to be cheap. That said, the most expensive is usually overkill as well, so, point is, make sure you know what you are ordering and who actually made it, cause rockauto is just a reseller.

yeah, I usually check out dealer parts sites for OEM part numbers and diagrams. Rockauto’s got a pretty extensive catalog too, just make sure you’re not going for the cheapest option, quality matters.
