I,m in the process of restoring a 1966 coupe. It,s a California car and does not have defroster ducts. Is this normal? I have a 65 parts car that has defrosters. Should I install them or not?

All the early mustangs had a defroster system, unless the buyer had the heater delete option. If it did,  there would be a delete plate where the heater controls were.

going to have to look into this further. Have the heater box and controls but no defroster ducts. How did they hook up?

The defroster ducts come thru the top of the dash pad. Remove the speaker grill, and you will see to holes on either side of the speaker. The ends of the ducts attach to a heater plenum which was made out of cardboard orginaly (see picture below). It attaches to the heater box with for hex head screws. The heater ducts and plenum are available new from any mustang parts stores.

After looking a little, it appears that some one added the heater box afterward. Ther was a hole chopped in the firewall for the hoses. They did not put in the defroster plenum. I am going to install the complete unit from my parts car.
