But you can't fully tighten the center bolt after carrier is bolted to the car.

I'm leaning towards one of these two methods:
1. Install but don't fully tighten bushing to carrier
2. Raise wheel assembly to ride height
3. Bolt carrier to car
4. Unbolt carrier and mark position of bushing to carrier
5. Jam something between carrier and RTA to maintain position of carrier relative to RTA while tightening center bolt to 81 ft/lb
6. Bolt carrier to car

a. When lowering old bushing, mark position of carrier relative to RTA
b. steps 5 and 6 as above
