Doesn't matter. As long as the "other bearings" are OK. The wobble is because the shaft has no support at the pilot end when out of the car. In other words the pilot supports the front of the input, and the yoke supports (in it's bushing) the rear of the mainshaft. Both will wobble out of the car
But if it has to much play with the yoke in than you more than likely need to replace the bushing.

It's probably worth tearing down and inspecting if there's any question as to condition. I've never used "special tools" but having an undersized arbor to install the cluster needles is DEFINATELY a plus. in "my yuth" I just used grease and my fingers, and maybe failed a couple of times.
But tearing it down will allow you to inspect the interior of the pilot shaft, the nose of the mainshaft, and those needles. Same for cluster shaft and needles. And, you have the two big ball bearings "out" where you can turn them easily and "feel" for roughness as well as see the races and balls.
