For those who have modeled the 4-place Bearhawk in a CAD program, I'm looking for a measurement. I'd like to know the perimeter of the exterior of the fuselage assembly at a station 76" behind the spinner bulkhead, with the station being parallel to the prop disk. If this is something easy to find, I'd appreciate the help. If not, don't worry, I'll try to do it in real life with a string, plumb bob, and system of pulleys and tubes. And some masking tape.
