1 Cut out the hole for the avionics fan. Filed and sanded it smooth. Drilled the four mounting holes. 2. Strain-relieved the fan wires inside the fan housing, Cut off the original connector and crimped on D-sub pins to both ends of the power leads. I will connect the fan just before the top skin is riveted in position, but first the skin has to be prepped and painted, inside and out. The section inside the windshield (on top) will be flat black. Underneath (just above the instrument panel), it will be light gray. I am going to research different fabrics and coatings for the top of the glareshield. 3. Hooked up the avionics fan and tested it. It works great. 4. Clecoed the top forward skin in place to check clearances and fit. The holes in the instrument panel attach angle had to be wrestled into alignment, but I got them to cooperate eventually. There is a rather large gap between the right side skin and the top edge of the instrument panel. I might have to install some sort of cosmetic shim there to take up the space. It also looks like the skin will need to be trimmed slightly at the rollover bars.
