[AJD] Model L steering box

[John Boehm]

In addition to your comment, I also received an off
list suggestion that the Model H governor bearing
might be close enough to work as it is a similar
tapered ball and cage bearing.  Since I happen to have
a disassembled H governor in the shop, I compared in
to the LA steering box bearing. While it was close,
the H bearing was still  thicker, larger in diameter
and the balls were larger.

By the way, this H governor bearing was at one time
obselete, but now can be obtained from Sharp's. Not
certain anymore, but I think Melanie  Sharp told me 
that they found a source in Germany for this bearing.
Comments, Melanie?
