ok, I'll bite...
To install an oem roof rack you need (2 sidebars, 2 cross bars, 4 corner covers, 8 longer bolts (the bolts you have in your roof now under your rain guard are too short) and the pads that go between the roof rack feet base and the actual roof)...
You should need to drill anything. the threaded inserts are already in your roof from the factory, just pull the plastic covers off to expose the bolt heads.
see post #40 in my build thread.. there is a link there to the parts list I used to remove the top to give you a feel for what I"m talking about... you can also see exploded views on olathes parts center website on the right menu bar...
