Hi there, I just bought a second-hand IS250C convertible (2009) UK version. There are two metal bolts coming out of each side below the rear small windows (see pic). Look like potential mechanisms for rear window handles? Could someone help me? They are quite unsightly and I would like to remove them and then cover the holes with the supplied plastic covers in same trim colour of the car. Can I do that? Thanks in advance Alessio
