KagyMP5

This is probaly posted somewhere but I spent hours looking and couldn't find it. I just turned 16 and im got a '03 mp5 and that DAMN roof rack looks hack and sounds horrible when cruising with sunroof open. so if anyone can tell me how to completely remove it, the help will be greatly appreciated. I have been able to take off cross members but after that iam stumped on how to remove the acuall "stand offs (mounts)" do I have to take off the interior roof panel to get to some bolts? and will the mazda dealer have the black strip to fill in the ugly slot where it used to go.

Thanks in advance,
Ian
