Just curious............I have a 69 Convertible and was wondering if all the 69 Birds--convertible or coupe, came prepped from the factory to have AC installed without major redesign needed to the firewall and engine compartment. I have not seen a Bird with AC and was considering having it put in depending on the expense and the work involved. Not sure what to be looking for under the hood. I would like to be able to take my car out on even the hottest days in the summer. Does the interior dash have to get ripped out and replaced??? I've got no idea. Anyone out there done this? Any insights as always are very appreciated.

The firewall is substantially different for AC vs non-AC cars. You would have to go with aftermarket AC. Several here have gone that route and can chime in.

You have a convertible. You can take it out even on the hottest days.

I have a '69 convertible with factory air, and the only time I've ever used the air is at the Woodward Dream Cruise on one day that topped 90 and I was sitting in the hot August sun idling for an hour at midday.

With the top up, the air conditioning is not all that effective. With the top down, you don't need it.

I put a zip down back window in mine. It's pretty pleasant on a really hot day with the top up to keep the sun off, but with all the windows, including the back one, down.
