Magnum Swap Question

As some of you know I am a few days away from swaping my Magnum 360 build into my 71 Dart. I know a lot of people use mini starters but I was just wondering if my starter for my LA 318 that is the car now will work on the magnum?

Or should I buy a mini starter from Summit? Or would a stock starter for a 01 Dodge 1500 work (Thats what the magnum engine came out of). Thanks in advance for any advice.
