I thought I would share the install that I did on my car and Wooster Kevin has done on his. Most of this is based on the experience I've garnered over the past 6+ years since I've put mine in.

My install was a retrofit done with the engine in it while his was done when the car was being restored so everything was open. One difference being where the bulkhead connector is on the firewall. Mine is close to where the original heater hoses came thru while his further to the right coming out in the wheel well. That allowed the hoses to be mostly hidden and the engine compartment to be kept much cleaner looking. I'll keep adding to this as I remember more details or answer questions. Hopefully it will give some of you ideas on how to do this yourself.

Javelin A/C Install parts list (partial)

Gen II ComPac - Heat Cool and Defrost - 68000-VUZ-A
Base Model Horizontal 4-Lever Control Panel - 49110-SHQ
Sanden SD 709 Compressor Double V-groove pulley Standard Finish - 04709-VUA
Horizontal SuperFlow Condenser 14 IN. tall x 24 IN - 03263-VUC
Louver for 2.5-Inch Hose 3.875-Inch x 2-Inch All Black - 49327-VUL are what I used w/o factory A/C. Will need 2.5" duct hose.
I used a 4-Way Diamond Bulkhead Plate for AC and Heater since it was in the engine compartment but others could be used.
A hose and drier kit depending upon what they want to use. I use a trianry switch with electric fans.
They will need to find 3 groove pulleys for the crank and water pump.
They will need a York to Sanden adapter plate.
They will need to upgrade the alternator if they use electric fans. They will need to use a double pulley on the alternator so that you have double belts.
Ford Contour fans fit the Javelin radiators perfectly.

Something that you must understand if you're going to do this, you need to spend time and money to insulate your car as well. The reason is because this unit is to small for the size of the car and if you push it hard, the evaporator core can freeze up. It's happened to me several times. Insulating the car and tinting the windows helps the unit keep the car cool inside even while driving across the desert in 100° + temps.

1.  What was your deciding factor in choosing the ComPac II unit?  It does have lower cooling capacity, and your recommend for insulating is a good one.

2.  What dash louvers did you use? If the AMC factory ones, how did you transition from the round duct to the rectangle openings?

3.  Did the VA defroster vents not fit at all between the dash and windshield? Or, why did you stay with the AMC defroster vents?

4. Why did you decide to use the VA ducts and not the factory AMC ducts?

Thanks John. I hope you find it useful. No I don't mind so here's your answers.

1 - Because it fits behind the dash! And the outlet placement works well. When I was at Vintage Air's factory a couple of years ago, it drew quite a crowd because nobody thought there any of the units would fit behind a dash like that. It even got videoed inside and out. I got a lot of compliments from the crew there.

2 - I will get the part numbers and post pictures on how I put the louvers in.

3 - I didn't have them to try but the factory one fits perfect and works fine.

4 - My car didn't have air to begin with and the pad with air I had was missing the louvers. I couldn't find any so I had to figure another way to do it. I also didn't have any of the duct work.

If you, or anybody else is interested in buying any Vintage Air, I have a VERY good dealer to work with and I always recommend him. I doubt you'll beat his price too. Call Andy at A Plus Rod and Custom. Tell him Keith sent you.

Hi Keith,

Thank you! 

Yes, the VA folks weren't sure what would fit when I called them last spring. I'm not sure if they told me, or I read it somewhere...the Prestone Javelin uses the big VA HVAC unit.

The AMC fan box is almost the same size as the VA smaller unit, so it would seem there'd be lots of room. My measurements indicate the larger VA units would fit.

My car didn't have AC, either, but my dash does, and I have the original ducts, and had the interior system in when I decided to change my mind and go after market, new, and latest technology.

From one of your photos, it appears you might have aftermarket front suspension....might it be from Control Freak?  I have such, though I haven't yet driven it.

What unit are you talking about? There's maybe an inch between the dash support and the heater box on this so I'm not sure what bigger unit would fit.

That picture of the black car is Wooster Kevin's car and he has the Control Freaks coilover conversion in it.

My car has a G3 Hemi in it with a Fatman weld in IFS. My swap is here. http://theamcforum.com/forum/hemilina_topic95889.html" rel="nofollow - http://theamcforum.com/forum/hemilina_topic95889.html

I added to my original post with more pictures and information.

That's a really neat installation and great photos Mopar_guy!! I'm sure many will appreciate this well documented thread.

Southern Air has some units that are packaged a little differently than Vintage Air and may be a better fit in some cases. Their MaxiCooler III and Superfrost units are really good. In some cases it's what fits over everything else! The dimensions of the Southern Air cases are a bit different from Vintage Aire, one of their larger units might fit where a VA larger unit wouldn't, and vice-versa.  They also have a "mustang style" under dash unit that looks near factory for the American and is perfect for 50s/60s cars, and a wider under dash unit that looks like a dealer installed unit for late 60s/70s cars. The Vintage Air Magnum Gen IV mounts under the passenger side and has ducting toward the center of the car (left end) similar to many factory installations. It would be great for a Rebel/Mat/Ambo. It's the only one that's configured that way.

The only other unit I've found that is much different as far as packaging is the Old Air Products Hurricane unit. It's a boxy unit that's about 12" tall (including duct flanges), 11.5" wide, and 8.5" deep. Wouldn't help with the Javelin, but might work well in other models. They have a side connetion and rear connection (for hoses) model.

Most places sell either VA, SA, or OA products, some customized to individual makes and models, some just dealers. There are some companies selling cloned units, I know Southern Air complained about at least one of their units being cloned a few years ago. Many units are similar, it's just different packaging after all -- AC is AC!! You could get the parts from a junkyard and make your own housing... it's been done before!

If it hasn't had a charge in it for a long time, do yourself a favor and replace the drier. It's most likely saturated and not functioning. Look for oil stains on the condenser. If there are, or the fins are coming off, you should replace it as well. That's what's going to make it work well. You might consider changing the hoses with new, barrier hose to keep the refrigerant in. Them old hoses are prone to leaking.

Yes, you can reuse the expansion valve as long as it functions. You won't know that until you charge it. The one in the 71 I did, worked just fine when I did it.

You're much better off running 2 belts with the Sandon compressor. As Cam mentions, it will slip with one belt. Replacing the alternator pulley with a double sheeve pulley should get you there.

The first picture was from my car when I added A/C. The second is from the 71. I didn't use the idler pulley. It would squeal when you first turned it on. If I were keeping the car, I would have used 2 belts because one isn't enough IMO. Plus, today's V belts are all junk. They simply don't last. Wooster Kevin has a 2 belt setup and has to replace them twice already in 5 years, because they wear down so quickly.

Not a Javelin, but I'm using the original expansion valve in my 63 Classic. It's charged with R-134a, but works fine. Also using the original evaporator and housing inside the car. The entire inside unit is original, but I'm running a Sanden style compressor with serpentine belt (4.0L) and a Chrysler LH parallel flow condensor with a universal drier. It all works well together. New hoses are barrier type. I wouldn't run 40+ year old hoses. I had to mate all the under hood O-ring fittings with the flare fitting inside, so had to have new hoses anyway. I do wonder if an expansion valve calibrated for R-134a instead of R-12 would work better.

The only thing that doesn't seem to work is the original temp control. It doesn't seem to make a difference where it is set. The compressor switched line runs through it, but I can't tell any difference when I move it. I only run the AC when it's over 80 outside, and the evaporator could be larger for the wagon, so it might be working. The AC was sized to make it more comfortable in the car, but it's not as cold as newer cars! Wasn't designed to be in the early 60s.
