There are lots of ways to search for parts. Numerous how to info on here on how to do it and, lots of info on Google.
I use partsouq.com and toyotapartsdeal.com.
I like the illustrations better on partsouq. The rest is not as clear. I though Toyota stealerships would have clearer illustrations of them all being a certified dealer for Toyota. Nope.
Did a search on toyotapartsdeal. Came up with a part number and confirmed it on partssouq. It was cool cause there was a pic of the part to further confirm that was the correct part.
On that bottom of the page for the part number (toyotapartsdeal)is this list of all the cars that fits that same part number.
I pissed some stealership parts guys
with this method. Some even ask me how I came up with the Toyota part number, or ask what shop I'm from.
