$416 feels a bit steep for the mudflapsYes, toyota does make these mudflaps without the First Edition logo. They offer them in black and red. I have a set on my 1958 in black.
The only thing is the front ones need to be trimmed. These are for the japanese market and they don't fit exactly the same. Fortunately, I just took a First Edition one and traced it, then trimmed. Perfect fitment and they reuse the factory hardware.
link here and can confirm, these are 100% oem new from toyota.
But at least you can buy it.
Thanks for the link.
