 one suggestion, If you decide to use screws. I found on the top of the cowl
and around to the sides it is better to use the floating anchor nuts.
F5000-08. The reason for this is the top of the cowl is not parallel to the
bottom of the cowl flange and it causes the screws to be slightly angled if
you use the fixed anchor nuts. With the floating anchor nuts the screw self
centers into the countersink and looks allot better.
