Looking for the size of the 3 strut nuts that are located behind the passanger seat... Not the center nut... I have a subwoofer box i want to install and the
mounting brackets are located on the strut. So i am going to add 2 nuts on the
Bolt but need the nut info...i do not want to mess with original strut nuts

I have tried M10-100 and M10-1.25
I am going to try M12-1.5... Not sure


Any help would be appreciated

 

The nut size is m10-1.50
