Hello all. I'm pretty new to mustangs, and yes I want to mod my 03 Mustang GT. My next mod is a thtottle body, but I'm concerned about warranty issues. I really want to change the exterior if I can do it myself. I know I can remove the rear spoiler and hood scoop, but how can I plug the trunk lid and hood bolt holes myself to keep water, etc from getting into the engine and trunk? I'm not concerned about it looking patchy and I'd rather not take it to some body shop. I'm trying to do a "sleeper" look. Thanks.
