If you have a muscle car, this site has a decal set for it. Ford, Chrysler, Chevy, AMC, Buick, Pontiac, you name it! The decal sets are available if you e-mail him and request a decal set for the make, model, and year of car you have. You can browse through all of the sets he has made up too. The sets are pretty detailed. I was going to make up a decal sheet for the Shelby Mustang GT-350H I'm working on, because the decal set that came with the kit didn't include the sticker on the air cleaner, the cobra emblem on the steering wheel, the cobra emblem on the trunk, or the GT-350 badge on the rear of the car. One of the kits he made did include all of that plus a lot more.
Hope this helps, it sure helped me out.
