Hi Rubicon! I am assuming that the snap that is bad is on the canvas. It consists of 2 pieces, the outside and inside piece with the canvas inbetween. You will have to take the entire snap apart which you will have to do by carefully drilling the rivit in the center of the snap off. The snap kit comes with a set of tools or metal forms that with the help of a hammer and a hard surface, you assemble and align the two pieces together with the canvas inbetween thru the hole in the canvas and tap them so they attach together. They sell an attachment tool in the form of a set of pliers which will make the job easier.
