Yeah it is actually very easy to find,you can see part of it on the outside of the box,there is a plug with i think 3 or 4 wires that plugs onto the box,this is the part,there are 2 screws that hold it on there.

 

ok thanks for all the help guys.

 

I just order the delete box thats for the hook up. I was gonna put it off for awhile but I had a great day at the yardsale. Almost sold all my junk. I'll post up pics when I install it.

 

I took out the ac in my 72 camaro. I used the original ac/heator box but fabricated it so i can cover over the the firewall and use the same mounting holes. It takes alittle work, fiberglass and hardware cloth but it looks great . PM me if you want , save your money and fabricate your own box.

 

I don't have a stock one. I bought someone elses project. I thought about making my own just like you say but meh, screw it.
