With the transmission mount removed, I was surprised at how little
support the transmission needed. Of course I wasn't mentally taking
into account the drive axles.

I see your point. I keep thinking that part carries a lot of weight.

FWIW to those who are curious why I needed a longer bolt....

When was initially modifying the mount brackets, they wouldn't line up
to the bolt holes to the frame. Along with elongating the holes in the
bracket that bolts to frame I made the hole in each arm of the
transmission bracket a little longer. I shimmed each hole:

which worked "ok".

But this along with removing even more material at each arm, gave me
pause to think about strengthening those spots so I welded a washer on
to each hole and back filled the rest of the hole. This "tightened"
things up and will hopefully add some strength to that area.

Thanks for the help people.
