Rag Joint or Vibration Reducer?

[DaveD]

I just rebuilt my steering column and have all new steering components as well as a new AGR steering box, I am at the point of putting things back and and need to decide on what do do with my steering shaft.
I am thinking about replacing it with a stainless spline shaft with a
1- 48 spline x 3/4-36 u-joint on the column end and a 3/4-30 spline x 3/4-36 spline vibration reducer u-joint on the steering box end.
Will this be OK to replace the rag-joint?
