       Dan,
           Here are a few weights and measurements for the factory
soundproofing. There are four different types.

1.Sides of fuslage                 3 lbs.     40.5"x 40.75"
2. Nose gear tunnel (for the IV)   2 lbs.     17.25"x18"
3. Nose gear tunnel ( " )          9 lbs.     17.75"x 56"
4. Firewall                     16.5 lbs.     34" x 65.5"

   The sound proofing for the firewall listed is not all of it because I
installed some under the floor. Whatever those dimensions are. As you can
see if a builder installed all of the foam you'd have a pretty nose heavy
airplane. Hope this helps.

            Don
