It is possible to do it yourself...it really isn't that hard. I did it for a friend a few years back and it worked out great. You can order some from Baltimorestreetmods.com or from Bobwhitedecals.com Both sites sell them but the bob white ones are a little more expensive but i believe they are better quality...Also both sites have an a guide on how to do the install. But mainly all you have to do is a certain mixture of water-soap (i forgot the correct amount) and apply them in a straight line (lay down a line of masking tape or painter's tape for this. Ohh yeah don't do it in direct sun light...this will limit the time you have to make an changes.
