[DeTomaso] Ladder-style engine bay brace

[gow2 at rc-tech.net]

The x brace in the deck lid opening will stiffen the carboard box but
there is a weak spot where the wells attatch to the frame. Only the ladder
box can really address this weak spot; not that the "X" would not help. I
have seen many cars with kind of  compromise which include both the
x-brace and a rear roll bar which tie into the rear deck hinge points then
come down and tie into the wheel wells. I have seen many of these and I
plan to start fabbing on mine soon.
