I'm looking to attach a gt body kit onto my lx. I know the front and rear bumper in basically a bolt on, with the front having rivets. I've got the mounting brackets for the sides, but need to know what type of screws I'm supposed to use???? Some say to use self tapping/sheet metal screws, but then I've also read people say NOT to use them and just use 3m double tape. Any suggestions??? Btw I hate the idea of being able to see visible screws on the gt kit. ???????
