Sullivan sells just the adapter off the end of the starter. If I'm not mistaken it just bolts to the output shaft of their starter, but I don't know if it's keyed or has a flat, or some other method to keep it from spinning. Even if it does, would be simple matter to go to local hardware store and get a bolt and nut, run it through center hold of adapter and just chuck it up in drill. If it has flat you'd need to grind off threads on one side of bolt to fit. You want the largest bolt that will go through the hold without cutting threads. You'd need an insert, of course.

Not like an LA 40 takes a lot to turn it over... mine would almost always hand start except on the coldest days....
