The outside wiper gasket has some felt surface where it contacts the glass. Yes, if sand gets there, when you lower the window it will scratch the glass. I just bought new ones for my 1991, the part numbers are 1266700138 and 1266700238. I am assuming yours are the same.
First you pull up the chrome molding that is on the outside. Be careful not to bend it (it has 5 clips that hold it to the car). Then the gasket. The clips actually secure the molding and the gasket at the same time. The gasket may come out at the same time with the molding.
It happens that I have the passenger side out and tonight I plan on putting it back on the car. I will take some pictures and post them for you to see.
EDIT: i bought mine from the dealer. First was 168.00 USD and second 169.40USD (shipping and tax extra).
