After searching through a pile of archived files on 1.44 floppies I finally
found this file. I had modifed my cushcraft about 7 years ago and had good
luck with it.. Many of the elements however didn't survive the move to NC. I
have spare elements but didn't have the dimensions. I have included the file
for anyone who would like it..

To do this conversion you need to remove 3 directors and trim one
director.  The remaining 6 directors then must be respaced.

The directors with the lengths of 35 7/8", 35 5/8", & 35 3/8"
should be removed.  The 35 1/8" director should be trimmed
the same amount on each side to a overall length of 34 3/4".
The remaining directors then should be respaced using the
drawing and dimensions below.
