I have a hot air heater that I’m trying to figure out how it is connect to the vent part that I’m holding, which when installed, will go in the firewall. (See the pictures). Somehow I have to run a pipe (or hose) from the end of the outlet of the manifold heater to the end of the vent. Does someone have this setup in their car that can post a picture where I can get an idea how to connect. This is for a 1935 car but maybe other years would be the same Thanks.
