Hi: I have a 1990 Accord LX. I need to replace the inside rear view mirror. I have a replacement mirror and could swap them if I could just get to the screws. The mirror's mounted on the underside of the roof. The screws are hidden by a cap. The cap's pretty tight and nicely flush with the roof liner. I tried prying the cap slightly but it looked like it wanted to start bending out of shape rather than easily pop off. Any suggestions? Do I need to slide the cap in one direction or another vs. trying to pop it off? Thanks. Kevin
