Pawnee hell

I have posted to the group before about this situation...but
after not quite a year of working the problem....the
Pawnee in question still does not have fed approval
for a tost hook. Needless to say a doctoral thesis
could be generated from the twists and turns....but
the basic facts a

1.) The aircraft is currently in Restricted Category...and
has wing extensions.
2.) The Denver FSDO threw their hands up...so the
plane was taken to Liberal, Kansas with the hope of
more cooperation there.

Does anyone have knowledge of a Restricted Pawnee that
has been approved for tow hook installation in the
last year? Prior to that it was not nearly as much
brain damage...but apparently a memo generated about
this time last year has produced this result.
