Was it the same as described here:

It looks good to me. But it would be extremely important for the 2 mounting bolts on the control arm to be absolutely tight and free of movement. Any movement would quickly make the bolt hole larger, damage the shaft, control arm and shock itself.
If it were my truck, after mounting, I would weld those 2 mounting bolts to the shaft and to the control arm itself.
