Should be just below the weld on mine.

Actually doesn't make any difference. My guess is that it's just how they set up the drill presses (gang drill presses) for that particular run.

On my 48 the zirk is 3/4 of an inch down from bottom of the weld to center of zirk.

later models had them farther down
