I added the reading light.  The panels on the bottom of my baggage are are remove in this picture.  The cable sticking up goes to the strobe power supply that hangs from one of the two 3/16" plywood baggage area bottom pieces.

The builder made some very nice seats with a contoured fiberglass bottom and a hinged plywood seat back, but they were covered with an ugly naugahide and not padde at all.  I took them to a local upholstery shop and had the leather put on  I have TemperFoam padding under the leather.  It was expensive, but I only have about an inch and a quarte of padding on the bottom and an inch on the set back and I can sit in the seat for hours without my but going numb.  I really didn't have the head room for a lower cost padding that would need to be thicker.  I won't say how much the leather cost so it can't get back to my wife.

The original builder filled the area between the stringers with foam from the firewall to the trailing edge of the wing and put on one thin layer of glass on the inside.  It was originally covered with the same ugly naugahide as the seats so I ripped it off and put on this padding from the upholstery shop.  If I were building another KR I would glass the inside like this.  It looks great, gives great thermal and sound insulation, and probably only adds three to five pounds.  I have carpet that I will put on the floor soon also.

The sticks originally had bicycle type grips.  I carved new grips out of teak and installed push to talk buttons for the intercom.  The left one is a perfect fit for my hand, and the right one fits my wife although she swears she will never fly in the KR with me.
