I know this might have been covered. Mounting lips and all that. but the ww rs lip i think is different. I purchased the lip used and the double sided tape was not sticky so i took that off and put new one on. However that wasnt substantial. I also had screws on each sides of the lip. the problem is tho on the middle of the lip on the under side, i cant put any screws there because its not flush with the bumper. Are the any alternatives to mounting besides the double sided tape? i dont want super glue cuz im pretty sure imma change the lip probably in a year. help me out
