4.0 SOHC pilot bearing

How critical is the location of the pilot bearing in the flywheel? Not knowing the shop that resurfaced my flywheel needed to remove the bushing around the pilot bearing, I only measure the location of the pilot bearing relative to the bushing. Now, with the bushing removed I have lost the location of the pilot bearing.

So far I have centered the bushing in the flywheel, then located the pilot bearing according to the dimensions I measured before. It seems the pilot bearing location is not critical but I am not sure about that. The Ford repair manual does not give any pilot bearing location dimensions.

You'll notice that it's the flywheel, then a bushing of sorts, then the pilot bearing. You'll also notice the bushing thing and the pilot bearing are both tapered...fit only one way. I just beat it in and it let be. Never had problems. The stub of the input shaft is pretty darn long. From my experience, the depth of the bearing isn't all to important.
