Rated 5 out of 5 by woody from Great replacement product My old heater box was literally in pieces when I removed it so it was necessary to replace. This box is great, came with all the internal gaskets installed already and already had the heater resistor installed. It is a bit difficult to install the heater core, but CJ Pony had a good tutorial online. It did NOT come with the gasket to seal the blower motor to the firewall so I had to buy that separately.

Rated 5 out of 5 by snoman_99 from awesome... thanks ! had to fix our Heater Core so decided to take care of the whole heater assembly and also picked up a new heater plenum. with our weather starting to change here in oklahoma we tested it out today and we had a nice heater going within the car and it was great to finally have a defroster!!!

Rated 5 out of 5 by Evan307 from Super pleased After having my heater blow up I pulled the old box out and as expect for an original part it was trashed. I found this and ordered it along with a new resistor, blower motor, control cables, and cowl seal to go with the new box. Got everything in and found out the box comes with a resistor already installed. Put the box together fitted perfectly nice and tight. Install went smooth everything lined up great. Super happy with this I'll be ordering another when I do the next one

Rated 5 out of 5 by GT junkie from Excellent reproduction! This heater box Is perfect. I would not have known it wasn't an original part by ford. Mine DID come with the heater resister pack installed. New heater core fit perfect.

Rated 5 out of 5 by KSU EMAW from Careful When pushing the clips on, be careful and wear gloves or push them on with something other than your thumbs. The clips will chew your thumbs up, very sharp tops.

I can not find a separate box for the 1966 Automatic....just the 2 speed and 3 speed. Will this work for the 66 Mustang automatic Coupe?
This will work if you currently have a 3 speed switch. The transmission type does not affect the heater box.

Just received heater core that I ordered. When looking at re-assembly I noticed that the heater box is cracked. Will HBA2 heater box fit my 66 mustang w/o air? and is it available for a two speed fan or just for 3 speed?
Here is the link to the 2 speed heater box.
