Ken,
What is the rear oil pan rail? Is this based on Paul's "hat section" design
for the MM?

Bill,
Nothing as elegant as Paul's hat section.  I used a piece of .065" x 1" x 1.5" 4130
square tube and bolted this directly to the rear housing.  It only extends
past the rear housing about 4 " on each side (one side a little further than the
other - the e-shaft is not in the center of the housing on 13b's) and is only
about 16.5" wide.  I will oxy/acc weld 0.125" 4130 tabs to this for the motor mount
rubbers and will use a spacer to get the 1/2" thickness required by the Barry 22002
mount.  Easy to fabricate!  I will build a custom oil pan out of 0.035 4130 sheet and
the motor mount tube will be the front wall section.  I don't have a power hack saw,
so I use a cut-off wheel or a manual hack saw for fabrication.  I'm also using thin
guage 4130 rather than aluminum because I can weld it with oxy/acc.  This will weigh
a little more but I can build it myself.
