When you guys stapled your bench cover on, did you then cut out the center (like the OEM was), or leave it covered? Instructions dont indicate anything with his regard. Also I found that the rivets used (on my seat anyway, whih look like OEM) were what is called tri-fold rivets. They splay out much more that the common pop rivet and are used primarily on softer surfaces, such as plastic, to prevenr pull through on blind holes.
