After reviewing many other builder's designs I made a bracket for the flap position sensor. This is one part of the kit where you are on your own to come up with a good solution. The flap sensor is not mandatory but knowing where the flaps are positioned lets you display flap position on the Garmin PFDs and it allows the VPX electronic power system to do some neat things like not let you extend the flaps if your airspeed is to high and moving the flaps in increments rather than having to guestimate flap position with the standard momentary on off on switch.
I also continued tweaking the fit of the flap actuator side panels.
