It's pretty simple. Where are you putting them? I replaced my GT badges behind the front wheels. All i did was get some dental floss and a hair dryer. I let the heat build up and used the dental floss as a saw. Use a level when applying the new badges and some masking tape. Level out the masking tape and use the tape as a guide for the badge to "sit" on when applying. It makes it go 10x faster and easier. Let me know if you have any other questions.
