So I have an update/question.... I ordered part number 42340-WAA04 from Toyota parts online and received a different looking part. I was wondering if anyone here can help me validate the part number? I entered the car VIN and it is supposed to be correct according to the website but I am now doubting that after comparing both parts.

Edit: Attaching a picture just not working right now :/

yours look like the new updated part number: 42340-WAA06
the boot looks different on the updated part like the one you got
