The strip of rubber across the top of the windshield on my '94 Pathfinder has crimped up and probably needs to be replaced. Two questions:
1) Is this a part I can easily install myself, or should I have a glass shop do it?
2) It's hard to tell if a small (2 in.) section at one end of the gasket has broken off--should there be an L-shaped metal corner piece that covers this? I looked at another old Pathfinder and only saw the L-shaped corners at the bottom of the windshield, not the top.
