I know you said you like doing things yourself, but I think you'll find it best to do some research and buy from a supplier. There are a few threads here that point out that there are some differences between decal sets - that is, some Indy's that are rolling around may have the incorrect decals on them. Some eBay sellers have been bad about this, and there' s a likelihood that a picture supplied could actually have the wrong decals.
Here's a good recent thread that detailed such an ordeal in regards to Indy Fiero decals.
