I'm ordering new rotors for the rear of my truck due do the factory rotors being rusted prety badly. I'm shopping at Rock auto,and the rotors have two different options for hole size. They have rotors with 4.63" holes,and some with 4.84" holes in them. Any idea what size I need for a 2001 2500HD?

On a side note,are Raybestos PG Plus rotors good? Of course the Raybestos site says they are great. Rock auto has them for about 60$ ea.

They are the larger size with the dmax. Had the same question when I did mine last year.
