Once those pins start wobbling they will wear the holes in the shift tower egg-shaped in a hurry. I've fixed that problem by threading the holes and putting a short bolt in from each side, and grinding the end threads off for a snug fit where the shifter pivots. A Grade 8 bolt will last a long time in an application like that, and if it wears, it's replaceable.
