Location: McComb, Mississippi		Collecting parts for my 61 polara. I am just looking for any pictures of a factory ac system and I have one question . Can anyone confirm that the firewalls between non ac and ac cars are the same? Any ac pics or info would be appreciated.

Location: The Great Northwest		I can absolutely confirm that the firewall on a 61 Chrysler NYer is VERY different for a/c vs non a/c. The opening for cold air to enter is very different than the opening for the fresh air to enter. It requires the cutting and removal of some firewall sheet metal to install the A/C air box on the engine side. I'm having some technical glitches with a new PC at the moment otherwise I would post a picture or two.

The firewall is completely different on an A/C car. My 60 Dodge was originally a non-air car. The previous owner modified the firewall and instrument panel. He started to reassemble it and stopped. I have finished the job (see black car pic). The white car is a '61. I used these pictures as a guide for the dual A/C line routing on my car. There are several differences between the 60 and 61. The receiver/dryer mounts are different... which makes the lines and their locations different. Things I didn't expect were the most frustrating... like the A/C-only glove box.

I had two parts cars -- one to pull parts from and a second to use as a guide. It CAN be done, but it was not easy -- even with two extra cars laying around! I still haven't installed the rear A/C line.

Good luck!

It was really hard to do. I was given a pile of parts from the previous owner and some of it didn't work or make sense. He had two A/C parts cars and made them both accessible to me. It turned out that my pile of parts were a mix of '60 and '61 Dodge parts. With the two cars I was able to take detailed pics and assemble a complete unit. I had to make a shallow glove box to clear the under-dash ducting. The wiring was a direct plug-in... but the devil is in the details. Clips, ducts, nuts and bolts, clamps, hoses... all are needed and almost all are unique to the model year.

Had it been mine before the conversion was started, I wouldn't have done it.

Location: Victoria, BC, on Vancouver Island, Canada		Christian, have you thought about putting an under-dash unit in? There are some reasonable priced kits out there for the whole job, and you can buy a reproduction Mark-IV Under Dash evaporator as well, (very popular as aftermarket A/C in the 50s & 60s) which suit these old cars. Vintage Air sells kits, and the Mark-IV repro. under dash unit. It certainly would be a lot easier than trying to put together a factory A/C unit as even the dash board is different, what with the duct work coming out the top. Here's the Vintage Air link.... http://www.vintageair.com/2014catalog/Pages%20from%202014%20Vintage...

My Saratoga has an old Mark-IV system but the under dash evaporator is an older version than the one that Vintage Air sells, and not as good looking.  I got it working again this summer with a new compressor and dryer. https://www.flickr.com/photos/mopar380/14772883745/

Location: McComb, Mississippi		Thanks for all the pictures and information. I am kinda leaning toward adding the under dash type evaporator that Ian mentioned. It'll be a lot easier on me and my wallet. This information is extremely valuable to anyone wanting to do the conversion. Thanks again. Maybe I can score a nice mopar cool aire under dash unit. If not , the mark IV is very nice too.

Location: The Great Northwest		Here are a couple of pictures showing the engine compartment side of an a/c firewall. In a previous picture posted by fenix, you can see a protruding sheetmetal intake that comes out almost flush with the firewall surface. The a/c version doesn't have any extension coming out from the hole. In all fairness, there is a clearly defined sheet metal lip that can be followed to cut out the extension that is spot welded to the firewall so it isn't all that difficult with a reciprocating saw. That being said, it would be awfully difficult to try this unless the engine compartment is empty and the dash is gutted like mine is because I completely gutted the car in preparation for being painted. Also, I was able to take an unlimited number of pictures of a 61 NYer that came fully loaded with options and is still in the original family since new. Once my car is completed there will be pictures posted.

My friend Ron, who owns my ex-1960 Polara put in a complete Mopar Airtemp under-dash system in it last year but it took him quite a while to find all the parts, - pulleys and brackets were the hardest things he had to come up with. He installed a vintage MoPar AirTemp under dash evaporator along with a Mopar RV-2 Compressor. He spent about three months of part time installing the stuff, making up the lines himself, but it seems to me that buying a kit with a Mark-IV evaporator would be the more sensible way to go. This is what he put in the Polara:

Location: Arizona		Ian, do you think Ron might be able to take some photos specifically showing how the belts are routed and the pulley's he used? Looks like he used 4 belts. When I added air to my 60 Matador I had to do a three belt system because there was so little room left between the engine crank pulley and the crossmember under the radiator. I'm wondering how he fit the four belts in.

Location: Vancouver Island, British Columbia, Canada		Hello jimntempe,
About 15 years ago I found an Airtemp under dash evaporator at a swap meet. I don't remember what I paid for it but although it was dirty it looked to be in good condition. I then commenced a search for a RV-2 compressor, brackets, 4 shiv crankshaft pulley and the remaining pulleys, tensioners and misc items. These items are not common in Canada as AC was not a common option in those days. As I spend several months each year in the Mesa Phoenix area, I would comb the various auto wreckers in that area. Finally, in 2012-13 I was able to find the last items at wreckers in Maricopa and Casa Grande. By then I had accumulated five RV-2 compressors and started cleaning, detailing and bolting the apparatus together. I'm a Mopar technician but I had very limited experience with AC systems but was determined to make this work. What a surprise, when after evacuation, leak testing and charging, the system worked. Wife is now happy to come with me on these hot summer days.

Incidentally, the 4 shiv crankshaft pulley rides about a half an inch behind and slightly above the front cross member.

I tried to attach some photo's but they will have to sized smaller first and I'm out of time right now.


Respectfully yours,


chrycotech (Ron)
