What kind of bolts? and do auto parts stores know what you are talking about when you ask for them? hahaUnless you need or use them, take the cross bars off of the roof rack! They cost you 10% of you gas mileage.
You will need to obtain four of the "shorty" rail bolts to fill the holes where the cross-bars attached, or you may have a leak!
On the 01, that is true...they changed that on the 03, I had to unbolt the cross bars before sliding them off the back of the rails. On the 99, prob no bolts. Just FYI...Just pop the back piece off of the roof at the rear hatch, unlock the cross rails and slide them off of the back of the plastic rails attached to the roof. once off, put the little plastic parts back on.
no bolts need to be removed to take off the cross rails.
