Call Total Performance, Grosbeck Highway, Clinton Township, MI. They sell all of the currently available types including a custom model that simply bolts on the front of the timing gear...has tab, no roll pin required. If you have a roll pin sticking out from the cam, then use the factory eccentric. There are two factory items, one thick and one thin for use with different timing covers.
