shermanfreak is right; probably get more help under the Autos section of the forum. However, I am a new member also, plus my concentration is 1/24 - 1/25 NASCAR. Here are a few links that may help you in your search for the Kulwicki decals:
http://www.slixx.com/
http://www.bsrrep.com/
http://www.smhracing.com/
http://www.geocities.com/nascar1love/index.html
You should be able to find what you're looking for at one of these sites; I would probably try Slixx or BSR first, as they carry a lot of top-notch decals and accessories. BTW, welcome to FSM; I think you'll find a lot of good info. and a lot of good people on this forum. At least that seems to be my impression so far.
