When you have them switched be sure to check for interference where the arm comes away from the pivot. My QA1 arms hit a gusset and I had to grind the gusset to allow the arm full drop down to the bump stop.Do this check before you connect the spindle.
I was going to comment on the lack of Zerks but these have delrin bushings and what looks to be a metal washer that contacts the body. I like this design better than the QA1 ones I have where the urethane bushing pivoting on the body.
