Drilled the holes through the firewall for the throttle and mixture cables. I have not yet installed the firewall shields around each cable exit.
In photo #2 you can see the series of Adel clamps I installed to hold the throttle and mixture cables.
And photo #3 shows the rough paths of the cable in the cockpit. I will install some Adel or other clamps to hold the cables away from the handles and the side vent.
