Installing driver side CV axle. No new ABS RING : (

I have an Acura TL 2004 5at.

I bought a new half axle assembly from Cardone- 66-4221.

The problem is that the new one does not have an ABS ring. Should I just take the one off the old one and put it on the one?

I called the dealer and they do not sell that part.

Does anyone know where to find this part at?

Please help or should I just take the old one off im not to sure how hard it is to take the old one off.
