Some of you might encounter rusted driprails. In fact, some driprail problems dont rear their ugly heads until you attempt to put on the mouldings. This gaping rust hole at the base of the driver-side rail gave us some problems. We didnt have any backbone to hammer upon, thus we had to support the driprail so that we could secure the moulding over it. Look for these problems before you start. If your driprails are in poor condition, have them replaced by a competent body shop.
