I am struggling with the cabin heat air box on my PA-12 conversion to the O320. Does anyone have input that is specific to the correct location of the pass through in the firewall? That information is not specified on the STC indicating it is not changed from the original. My firewall and boot cowl are not original. Nor is my cabin heat airbox which was not mounted on the firewall as it was on a stock PA-12 with the Lycoming O235. If anyone has a part number for the correct cabin heat airbox that will be helpful as well. Even more helpful would be photos of the completed installation.
Happy Landings,
