3/1/19 2.3 Hours With Norma's help, installed padded clamp to bottom edge of baggage bulkhead. Ran comm coax up through clamps to comm antenna. Secured comm antenna on roof. Will have to add larger backing plate and/or L angle as roof skin acted like jello. Tried sever different locations for ADSB box. Will have to remove my bright idea of an extra bracket on cabin side of firewall. ADSB will go just to right and below of comm/xponder in photo #1.

3/4/19 2.1 Hours Drilled out three rivets and removed short L angle bracket below xponder. Drilled four holes for ADSB unit and clecoed into place.
