i used to have one of those swamps on me 56 oval vw
but it ran off 12 volt it work but not that good
and it cost like $500 bucks

I had a 55 ford pickup a while back . Me and my soon to be wife decided to drive to
Augusta Ga one very hot day. We were drinking in those days ( quit for over ten years now) and had a cooler full of ice and other stuff. Anyway I got the idea that if I took a piece if cardboard and made a shroud from the open cowl vent down toward the cooler full of with the cooler open it might cool us . It worked quite well. Cost about three bucks for a cooler 100 mile round trip drive.

Remember that R12 is like a 100 bucks a pound and you will need about a pound and a half.

R134A is less expensive. It runs at higher pressures. Remember too that R134a cannot tolerate the refrigerant oil required for R12 and vis-verse. So you must clean every molecule of the opposite refrigerant out of a system before switching. Use methanol. Make sure it dries out completely. You must throw the opposite type dryer away and replace it with an "unpoisoned" one.

Use saftey glasses!! The pressures involved in refrigeration are FAR FAR FAR higher than your normal experience. If refrigerant is blown under your skin the only recourse is immediate amputation of the limb. This is to prevent death. Also watch the truely "instant" frost bite.

Have fun!

Too bad I have no clue about nothing on air conditioning systems or else I would know what your talking about there kcress. heh

hmmmmm HC 12a.... Sounds almost like "batteries that never wear out" or "air filters you never need to clean" heheheh..

Haint heard oh that there stuff B4. Thanks Denny.

you should hang around me for a summer at work. there is a co worker that calls me Captain A/C of America the first time he called me that he was doing a superman stance with a " cape " on, i about died from laughing

i think i found the cheapest source yet for A/C www.streetrodstuff.com $329 for a heat -ac unit with the controls, made for little cabs

Honestly, by the time you match a used condenser, used compressor, replace the lines, match a controller and modify the ventwork, you may be better off to spend a couple hundred extra dollars and get the new system from vintage air.

just my $0.02

This looks like the way to go,but I am curious as to why it's not being promoted more aggressiveably. I'm going to do some research on this.

Ken, their shop is about 10 miles from my house. Maybe I'll slide over there one day and scope it out.

It may be the promotion is trying to keep below the view of some govm't overlord's notice. They are getting real testy about non-licenced (recycling, air quality) refrigeration work.

Agreed, but if this stuff is all that it's cracked up to be it would just about eliminate the need for the gov't to be involved. Though I don't use it, I am licenced.

Thanks for the offer Richard, I am very curious.

Read this epa site stuff......dont always agree with the epa but they do have some testing resources. Also, the word illegal pops up regarding the use of some of the gasses in automotive A/C systems. Why use a substitute when an R134 retrofit is so easy?

I am currently using 2/80, I only have 2 windows, so you gotta go a little faster.

On a more serious note though, I have been looking through some of these posts and have seen some very interesting things. Some good kits and alternative cooling agents, and I would like to say be careful what you buy to put into your AC units. Buy from a reliable source, and make sure what you get it what it says it is. There are some very good cooling agents out there that you don't want in your AC system, like butane, propane, and a few other nasty little highly flammable gases. Most I have seen here look good, but just make sure you research what you get. Many get put on the market just long enough to get rid of and then they are gone.

My partner in grime and myself just picked up an '82 Dodge P/U for parts. When we got there and looked it was pretty burnt up. So hot inside it had melted all the aluminum parts off the steering column and most of the metal frame for the dashboard. We started talking to the guy we got it from and he started telling us the story. Seems like his son was driving it and it started to smoke from under the dash so he stopped and got out. It immediatly burst into flames and he called the fire dept. It burned so hot so fast that it was almost out on it's own before the fire dept arrived, 10 min later.

So I'm not sayin', I'm just sayin'.
