[Sonar] Help needed with Spreader Repair

If you can keep the currently plate - that would be best.

You also have the option of using the existing holes.  I did this by making
two aluminum plates instead of using the factory stainless.  Then you can
drill holes to match the existing ones in the mast.  The aluminum plates
won't cut into the thru bar.  Any hardware store can sell you a strip of
aluminum that you can bend to the mast shape.  Mine are about 1/8 thick.

Whatever you decide to do, it is important to use a pair of clamps to
slightly compress the mast side to side while you drill the holes through
the spreaders into the thru bar.  The bolts or clevis pins should fit
tightly and exactly into the spreaders and the bar.  Sand and file the base
of the spreaders first so that they fit snugly to the side plates with the
new angles that the thru bar give you.  Then when you release the clamps the
mast will expand against the base of the spreaders giving you a tight fit
and preventing any motion that will cause wear in the future.
