90mm vs 100mm - that is the question

[tyrone27 at gmail.com (Derrick floyd)]

well I have used both 90mm and 100mm axles on my car.  last time I lined
them up which was a few years ago they where the same kength if I remember.
the 4K can take 90 or 100mm cups and it has the clearance for the shim
kits.
