Hi,

Our manuals don't indicate a size. I can tell you that the threaded diameter is usually either 6mm or 8mm, but I don't have the thread pitch or length.

I attached what I believe is the bolt you need below. It includes the OEM part number, but please confirm that is correct for your vehicle.

I hope in some way this helps.

Take care,

Joe
