Hi Shvegel-----no screws---held at both ends by tail lght surround,and trunk lock, but
if you look under you will see a screw hole at both ends,just left side of the gas cap---at right end,
and one just right of the SL badge, but on mine no screws in those holes so did not fit screws in to there.
so any body let me know if there are screws in yours,.regards.
Perhaps mine does not line up with hole,----will take a look tonight,regards.
