If the length of the turnbuckle being removed is over 14" (356 mm) a toggle must be
used to compensate. Be sure to change the headstay length measurement to reflect the
use of this toggle.
Length Check: Check your length by opening the terminal, removing the "cone", and
placing the fitting on the wire. The distance from the center of the eye at the top of
the wire to the end of the stud should be equal to the pin-to-pin headstay length
less 8 / " (216 mm).

If the length of the turnbuckle being removed is over 15" (381 mm) a toggle must be used
to compensate. Change the headstay length measurement to relfect the use of this toggle.

Length Check: Check your length by placing the rod fitting alongside the rod with the
nosepiece in its proper position. The distance from the center of the eye at the top of
the headstay to the end of the stud should be equal to the pin-to-pin headstay length
less 8 / " (210 mm).
