    If memory serves, they were 12mm. At least before the rust consumed them. Probably closer to 11.5mm. I needed vice grips to get them off.

    Lol I think he means it took a 12mm wrench to get the nuts off

    Which isn't what the OP asked .. @Wyoming09 answered the original question

    Whatever Toyota put in there, I found it was down a half size or so due to the corrosion.
