What type of Mini starter do I need?

I need a mini starter for the 360 I dropped today. I made a bad mistake and bought one off of e-bag. Of course it doesn't fit. Question is...which mini starter would fit my 76 360 motor. I will post pictures as soon as possible. Thanks for the help. And by the way, the drivers side TTI's where a M.F. but I got'em in.
