I think I have a couple screws loose...............Causing my Sunroof to rattle!

So I need some help.  When I hit highway speeds I notice that my sunroof rattles quiet a bit.  It only rattles when closed.  When I open it the rattle goes away.  I have checked the wind visor and it is not causing the rattling.  I got up in the sunroof and it looks like I am missing a screw in each side.  I have attached pictures for review.  Can someone else check your sunroof and see if I am in fact missing a couple of screws?
 
Thanks,
Eric

Just checked it out, and there are no screws in mine. So that must be normal.
 
As for the noise, could be one of the little plastic parts that ride back with the sunroof.

ive seen this before on other vehicles,it is those little plastic pieces,at least it was on those,but you should be able to go back to the dealer and they should replace them

Thanks guys I will look into the little plastic pieces.

we just had a suburban in our shop same sunroof setup thos plastic pieces should take care of it. our price is like 49.00 for the pieces and the rattly normally comes from the rear water diverter its a metal pieces held down by platic clips!!! WAJ huh..
