We used 50mm roller bearings. I had ARP send me some 1/2 bottom-7/16 top stainless studs with 12pt. nuts for the center hole, and 2 outboard holes per side. Works awesome!
How was your experiences with the Ritter block? Have you done a few of them? And do they take a lot of work to be ready for use? I was considering one, but, the expense is borderline for myself. You know the old saying, You cannot exceed the speed of your wallet.
