i got a 2000 mountaineer and i wanna take off my roof rack. i know lots of peopel have doen this. After i take it off, can i just put the bolts back in and be set? And there are 4 other holes that a knob of plastic goes in from the roof rack. DO i need to plug these up and how? or can i leave them alone. My fear is water will be albe to leak in the cieling and into the cab. Or The holes will rust on the inside. Thanks.
