Today, I begun by drilling the forward skin; Quite a lot of holes on the firewall side and on the ribes that have to be positionned correctly before drilling.



Then I fabricated the brackets for the fresh air vents(hot air will come through the firewall from the engine compartment). I'm not using Van's vents (on the right in the picture), but aluminium vents I bought from Steinair.



Here one of the brackets and on the left with the vent installed.



And here the panel installation. All in all a lot of time and fiddling before this result.
