While waiting for the installation kit for the 5th bearing, I decided to go ahead and mount the engine to the airframe. Since I didn't have an engine hoist, I used 4 hooks hung from the ceiling joists and some nylon ratchet straps.
It turns out, I was waiting for nothing. The installation kit had already arrived! The kit contains the necessary drill bits, reamers, and jigs to finish the 5th bearing installation.
Once the holes have been drilled (and reamed), the steel locating pins are driven in.
Total Time: 7.0 hrs.
