Paul, I expanded the notch in the S-beam to provide .062 clearance.
This required removing .4375 in from the front flange and .375 in.
from the back flange.  If shorter bolts (AN7-20) can be  used, the
back flange will  only have to be reduced .125 in.  I have ordered a
set which I can test tomorrow.

Now we need a picture of the installed reinforcements.
