So it was an easy fix. At first I was really frustrated because I figured all I needed to do was just clock the wiper arms where I wanted them to be. Then When I turned the motor on it wanted to drive the arms into the cowl! So I pulled them and observed where the arms were wanting to park, which was straight up. Then it occurred to me I had the transmission arms on wrong pivots. Switched them and all is now well!
