Mini starter issue with slant 6

Just for the record, I take apart the bendix of both of the starters and I think it's possibly to make work the mini starter with the bendix of my old starter, but that will require some work of a machinery shop, and that will be more expensive than the cost of the starter. Otherwise, overhaul my old starter will lead to the same situation, because the actuator was broken and it's quite expensive. The best decision will be search another starter that fits to my car, without any problem.

Thanks everybody!
