Vintage Air did a presentation at Ididit in MI. The real difference between R-12 and 134a systems is the condenser. R134a isn't as efficient as R-12 and requires more tubes and fins in the condenser. Give them a call and explain what you are looking to do and they should be able to point you in the right direction.

Hey Andy. As Junky says. All vintage air stuff is 134a I have gone with a 24 x 14 x .83 condenser. The one they use for the sure fit system is 22 x 14 x .83. That size isn’t readily available here in oz. I ended up going with the slightly larger one. I don’t want to let too many secrets out but I think this system is going to look pretty trick. I’m adapting some 61 Pontiac ac controls and vents etc so that it all looks period for our rhd cars. I’ll post some progress pics over the next couple of weeks.

The General rule of thumb is, as long as the condenser was designed for R134a going larger is the best option. The 22" works well but the 24" will shed more heat. Keep us posted on the build pics we love to get photos of what you guys are cooking up!

Hi all. So I’ve managed to get my ac up and running. I used a gen 2 super unit. I can tell you for such a large looking car I spent a lot of time up under the dash making sure everything would fit. I ended up sourcing a 61 Pontiac heater control panel and adapted the switches, thermostat and pot slider (for the heater valve) to that old unit to make it look like it’s meant to be there. I also thought I’d be super authentic and sourced two 61 Pontiac dash ball vents. Turns out that even though the Australian dashes are from a 61 Pontiac the ends of the dash have a different profile. So the vents I sourced aren’t quite going to fit. So I have a bit of work to do with the face vents. I’ll post some pics once I have those fitted up nicely. All in all I’m pretty happy with the unit. It certainly pumps out some cold air. I have turned the old heater control levers into the two floor vents and made a new blank polished ally facia to replace the old heater control one. I still have to do something with the glove box also. The unit protrudes about half way across where the glove box sits. I’ll cut the glove box down and make it fit. The old radio I had to slice a tad off the back of that also. It didn’t work but I like to keep things inside looking period and original. I did use a 2 inch larger condenser than the usa left hand drive ready made kit. I used a billet industries compressor bracket. Although they’re exy it was worth it. I’ve made brackets before for certain things and there is a lot of back and forth measuring and cutting and modifying. So well worth it in my books. If anyone is interested I could put together a list of parts used. I got my hose fittings locally from Ashdown Ingram for anyone going down this path. Had a local guy crimp all the hoses and gas the system for me after I had fit everything. So anyhow I’ll try this imgur link or a few pics to have a look. Hope it works.

That looks pretty good Jas. I’d be interested in what parts you used if possible.

The main hardware I used was.
Gen 2 super. 61005-vzu-a
Compressor va047001-suq
Bracket bs10421 ( billet specialities)
Drier with binary switch 07322-vuc
4 diamond bulkhead VA388600-MBA
Condenser 03263-Vuc 14x24
Controls VA49110-SHQ

So with all these parts I ended up manufacturing my own condenser and drier brackets. I had previously bought two new replacement firewall bulkhead plug/sockets from summit racing (American auto wire plugs ) and added the wiring in one for the main power supply and the binary/conprsssor wire. Inside the car I disassembled the old radio took out some of the backend garbage and remade the case to shorten it down. It took a bit of courage on my behalf to do this because I hate knowing I’ll never be able to have that working again. It wasn’t working in the first place so that helped my decision. I made my own brackets to mount the evaporator unit up under there. All I can tell you is one goes into a nutsert into the plenum chamber and two angle type brackets mount with counter sunk bolts to the under side lip of the dash. As I said in my other post, the glove box is still in need of some trimming down. About half to be axact.
The hose and the fittings were all from Ashdown Ingram just because I couldn’t get VA stuff in exactly what I needed. The controls were the interesting part. I started with a va control unit and just took it apart. I had to start with that just to see how the switches worked and the value of the heater potentiometer. I now know how they all switch etc. and could potentially use generic switches and whatnot from an electronics shop. I got a 61/62 Pontiac heater control unit and went to town on it. Without too much detail on modifications to get it all working from the old school unit. I can say that the fan switch and the heater potentiometer are mounted directly to the unit. And the thermostat and vent control switch are mounted remotely and operate via cables.
The dash/face vents I’m still working on. I have a few ideas there to keep it looking original and period. I know there are options for those from vintage air but I’m not completely sold on those just yet. I think I’ve covered most things. It’s certainly custom and one of a kind. And the main part is it’s out of sight !!!! Oh and it certainly has enough cooling for QLD heat.
Jason.

Thanks for that Jason, interesting read. My 62 is radio delete, so won’t have to worry about that and glad to hear you are happy with how it cools. That has been one of my concerns.

I just might have to give it a go myself.

Hi, not sure if you are interested, but I have a number of original '62 Impala Air Con parts that I was collecting some years ago to instal in my '62 Convertible but never did because of the difficulty. These parts are for the US style dash but converted to RHD at the time.
Cheers,
John, Sydney
