You might have to contact ATI directly - either by email or phone and see if it is possible (that is if no one has done it or knows of it being done)

ATI 877-298-5039

Thanks,Matt

Will have yo see if they sell just the outer shell or if someone has stock size laying around that you can scavenge -

Do you have to send them the balancer and they do it or can you buy the new ring and do it yourself?

If you can do it yourself are you able to do it while it is on the vehicle - ATI give any specifics?

Thanks,Matt
