[Shotimes] LSD Conversion KIT for the SHO? Any comments?

[Mike Kopstain]

Leigh,

Pop it back open to make sure they are all seated correctly.  Did you use
assembly lube or something similar?

In cases like these, I'd love to see someone grab a micrometer and compare
the thicknesses of their old bearings to the thicknesses of the new
bearings.
