It's not lifting it that's hard, it's lining it all up and sliding it home. I always use the plastic alignment tool but it isn't always so easy to get the box to slide home. Sometimes an assistant spinning a driveshaft in there seems to help the splines mesh.

The last time I did one was in my /6 '87 D150. I ended up using allthread dowels in the top two holes of the bell, got it started and put nuts on so it couldnt fall, then carefully slid it into place. I had planned to replace them with bolts after it went in, but the allthread is still in there with nuts on it. Should hold up to the massive torque and horsepower of my 1987 225cid! I did use the right bolts for the bottom two bolts.
