35.    The  cowl  has  a  unique  method  of  mounting  that  allows  easy  installation  and 
removal.  It is secured with 3 3mm bolts, 2 on the lower external portion of the cowl 
and one mounted from the interior of the fuselage.  The cowl hangs on 2 hooks and is 
secured  at  these  3  locations.    I  chose  to  use  2  of  the  EF  Thumb  Screws  for  the 
exterior mounting and spray painted them to match the paint on the cowl.
