gas tank which mounts up to yet another bracket that bolts up to the mount for
the lever shock. This kit transfers the shock loading to the frame point
that was designed for it. The down side is there are six pieces requiring
16 new holes in the bodywork and the brackets are bulky. I removed mine
after I found the tire on one side was rubbing against the bracket in the wheel
well.</font></div>
<div><font size="3"><br>

<div><font size="3">#3 single bracket direct to the frame. This part is
unique in its appearance in that it has a serpentine shape, mounts to the frame
where the lever shock mounts and reaches up to accept the top of the
shock. It has been said that this bracket will crack the frame since it
has a long lever arm and could apply additional torque to the mount. But
a quick vector analysis indicates that the forces are parallel to the long axis
of the bracket and the loading on the frame will be not significantly different
