mINE WAS EASY TO INSTALL BUT AFTER ABOUT 5 YEARS IT SPROUTED A CRACK. wISH i STILL HAD THE RECEIPT FOR THE LIFETIME WARRANTY. tHEY FIT REAL EASY AND LOOK DECENT. Sorry, just noticed had the cap lock on.

Maybe it craked because I didn't follow the silicone glueing instructions correctly. You want the cap to expand and contract correctly with temp swings. Thats why you need to glue it down in the correct locations.
