pm buellpartsguy he should be able to get you part number and maybe even the decal , I am guessing the decals are probably no longer made and few of them left or they are only going to make a very limited amount of in the future. because there is not much demand for the stock decals, only demand i can think of is few people like you wanting them and replace for insurance repaired bikes. good luck !
you want to also try calling Buell customer service to see if they can find you some or tell you if and when they might be available and where to get them at.Buell Customer Service at Harley-Davidson: the numbers are (414) 343-8400 and also (414) 343-4056 .
