I have a 5/80 FJ40. The console is missing. The heater for the rear is missing. I understand that rear heat was an option. Below are some photos of the existing piping at the firewall and into the front heater. It appears original. What are your thoughts? Did my 40 ever have a rear heater? If it is the piping at the firewall correct for the floor mounted heater. It appears to be correct for the console heater.
