Hi All:

Next week I am getting ready to cut out for the wing attach holes on an old L-IV fuselage.  I am just a little confused on the height of the front and rear spar cutouts.
Are they equal in height from the top of both the front and rear spar  (front 13.5" rear14.5" from WL 22) and where exactly is the measurement taken for the front spar.  Is the front spar an inch higher than the rear spar cutout, and I assume that both holes are 6" long.  Any info would be greatly appreciated.
