I have a 68 Camaro Big Block with AC that I'm restoring graemlins/thumbsup.gif . I am in need of the heater box that goes under the dash. Are all these heater boxes the same in 68 regardless if the car was a big block or if it had AC :confused: ? Will a 67, 68, & 69 Camaro/Firebird box work :confused: ? Thanks!

The box is the same if your car had A/C with either a Big Block or Small block, non A/C inner boxes are completely different than A/C boxes. 67 Camaro with A/C should be the same, 69 Camaro is totally different. I do know the 69 firebird interior ductwork is totally different from a 69 Camaro's ductwork. The 69 firebird ductwork looks alot like 68 Camaro ductwork but I don't know if any year firebird ductwork would be a direct swap into a 67/68 Camaro.

How can you tell the difference between an AC box and an non-AC box? I found one but the guy is not sure if it was for an AC car. Rick's tech guy told me the box was the same for AC and non-AC regardless SB or BB. He also told me 69 would not work. Man I'm confused.

Non A/C inner ducts have a hole in the top closest to the transmission hump for the blower motor resistor. A/C blower motor resistors are in the suitcase in the engine compartment. An A/C duct is also deeper (front to rear) than a non A/C duct due to the flow path the air has to take. A/C ducts also have two dampers inside them, while a Non A/C duct only has one.

Thanks for all you input Mark! Can you look at this Ebay item # 2446652922 and tell if it is for a BB AC car?

Dont mean to jump in. That box on e-bay is a non a/c box.
An a/c box will be much larger. Here is a a/c box for a 70-81 with a/c. The one you are looking for will look similar. There is a good bit of duct work that goes along with these boxs and they can get expensive. I sold 2 a/c boxs with duct on e-bay for a small block 68 and brought in $400+ for each. Finding a BB a/c box may be hard to find?

Its a Non A/C heater box with a Big Block heater core in it from a console equipped car.
An A/C heater box looks like the one in this auction from a 70 el camino. Note the vertical rectangular shaped opening on the back of the inner duct that matches the same shaped opening in the firewall. Also not that you can't see the heater core looking at the back, as it is enclosed by a rear cover plate.
