What exactly does that little tab with the stepped stud on it do?

We have one of the Lakewood bell housings we use on the dyno, and I thought the one starter bolt hole for the 130T flywheel was just drilled in the wrong place.

For the dyno, it's not really a big deal. The upper bolt fits okay, and on the bottom one I just use a c clamp.
