Apparently, it’s a 5.5mm according to some instructions I had. I used a 7/32” (which is most likely the size). That size is also used for the fender liner on the inside of the wheel arch - same screws used on the fender liner.
My vote is for the 5.5mm. I have seen them used in other applications. I thought all of the major automotive manufacturers hadn’t used SAE fasteners since the 80’s.
