Datejust Movement?

[asikonfun]

Hi, I have a broken Rolex 36mm Datejust movement, as the main spring is broken. I was just wondering which movement piece I'm supposed to buy? I'm not sure on the exact model or anything, and was wondering if it's available to buy a new movement off ebay or something.
