AM14U Sonic Shifter Upgrade

[Shu]

I am trying to upgrade the AM14U with the sonic shifter. I am having trouble figuring out what goes on to the output shaft. I removed the bearing from the inner plate since there was already a bearing in the sonic shifter. Now there is a gap on the output shaft between the inner plate and wheel assembly. Do I need to add a spacer? I also can't figure out the reason for the extra .5" hex bearings in the upgrade kit. They seem to be redundant.
