Sunroof on a 2005 GX470

[Kansas GX470]

Just bought a GX.  The sunroof is not working well.  I have greased it up and made some adjustments and it is a little better.  I really will never use it so I don't care that it operates well.  But it does leak air and make noise at highway speeds that is too annoying to ignore.  It appears to be off center a little and has a larger gap on the passenger side.  Would it be worth the trouble to order new perimeter weather stripping for the glass?  It's that or I caulk it shut.  Any feedback is appreciated.  Thanks
