Does anyone have a 337 for an airbox for the 165 powered Cruisair. Since no Cruisairs actually left the factory (or at least that is the story) with a 165, all of the 165 powered Cruisairs have modified or completely different airbox,s. Does anyone have a 337 that could be used to show a clueless IA how to write one up? Has anyone used a Stinson airbox and gotten it approved. Any help will be appreciated. Thanks, Grant.
