I took the deformed one to a coop and a bike shop. They didn't have the cage and balls at either place. The bike shop was going to suggest reusing the cage and just replace two balls that had fallen out but I wasn't too crazy about that idea. The coop had loose balls in a small jar, which was probably recycled, and the shop had loose ones as well.

I just went with the new loose balls same size plus a one or two more and I think it came out well. It's no longer rough and is smooth.

Thanks for the great advice guys.
