Aren't the lower holes in the trans case threaded for bolts that come through from inside the bellhousing?

Instead of a transmission jack, I use a long 4 X 4 post across the doors with the windows rolled down, and a cable "come-along" to suspend the transmission for removal and installation. It's a lot simpler than trying to work around a jack that's taking up a lot of floor space.
