Concerning your measurements recently, are your cockpit closeout ribs 
completely sealed?

Angier,

 

No.  I have sealed the stub wing - outer wing joint (white tub caulk) and that changes conditions in the main wheel wells.  I plan on "booting" the control rods and actuators that pass thru holes in the cockpit closeout ribs before winter arrives. 

 

I have been looking for the old IV type boots (about 6 inches long), especially to cover the inboard door actuators.  If anybody knows of a boot source, that info would be appreciated.

 

On long flights in the winter my right hand gets chilled from the cold air coming up the elevator trim wheel opening in the console.  I am sure my heated air would be more efficient should I close off those openings.  However, I am sure that the rear canopy seal will then have to be improved since the low pressure cockpit will still be seeking air.
