I haven't seen Peter's new LCA pivots but if there are flats cut into the shoulder of the LCA pivot just hold that on the backside and torque to spec. Then slide the LCA with the Delrin bushing installed onto the pin.
Same for the strut rod actually. When you slide the LCA off the LCA pivot, remove the double male from the end of the strut rod. You should be able to get on the hexes of the double male to torque the nut on the backside of the LCA. Normally you can grab a couple hexes on the double male with the strut rod assembled, those 67-72 sway bar tabs may be getting in your way.
Then, when you slide the LCA back onto the LCA pivot, just line up the aluminum strut rod tube and start threading it on when it reaches the end of the double male already installed on the LCA.
The delrin LCA bushing will spin on pivot shaft, so, the pivot shaft can be torqued to spec all by itself in the K. Same for the strut rod. Once the double male is tightened on the LCA all of the adjustments will be done with the jam nuts and the threaded tube.
