Alright, classic Mustang guys—here’s a heater box for a '67 or '68 Mustang that came factory with air conditioning.

This is the main plastic housing assembly.

Just to be super clear: it’s the box only.

No heater core, no evaporator, no cables or doors inside.

It’s just the bare shell, so you can rebuild it with your own guts or use it as a core for a custom setup.
It’s brand new and unused.

Since it’s unbranded, it’s likely a reproduction piece meant to take the place of the crusty original that’s probably cracked or broken by now.

If you’re piecing together an AC system from scratch or need a solid foundation for a resto-mod HVAC system, this is a great starting point.

Check your fitment before you buy, but if you’ve got a factory AC car from those years, this is the one.
