I bought an All Balls kit from a member of a different forum, so now I have some measurements. The height of the stock lower bearing assembly is .718". The tapered bearing is .563" tall, so we need .155" of spacer under the bearing.The lower washer #99-1054 is .115" thick, while #99-1011 is .183". The metal part of the seal is .025", so with the .115" washer would be .140" for a total of .703", which is close enough.
At the top end, I had a surprise: the top of the inner races I've used before fit neatly inside the nubs on the bottom of the adjuster nut, but the top of the All Balls part is much larger diameter, and the upper washer Must be used. The washer is .078", and the upper seal is another .025", so if too thick of a spacer is used on the bottom, there may not be enough threads on the stem for the adjustment nut to fully engage.
