It's my guess none of the replacements can contain any R12. Why would it be legal to sell anything with R12? All of the "R12a", "R22a", etc types I've seen are really propane. I do think the new normal retro fits will use propane since it seems to work very good for refrigerant even though it is flammable.
By the way, I just saw cans of R134a in Walmart the other day for $4.88 a can. I'm guessing R134a will not be available for sale pretty soon.

CORRECTION: Per the official Red Tek 12a installation guide.
Red Tek 12 a refrigerant is installed through the Low side service port and is charged as a liquid into a "0" atmosphere condition. Do Not install into system where a Hard Vacuum exists. Danger!! Do Not install in High Side Service Port.

Although RED TEKĀ® 12a is developed to give similar operating conditions and capacities as R12 and R134a, this product is an Alkane /Hydrocarbon and comes from the same hydrocarbon family as propane and butane. It is extremely important to know that; Commercial propane and butane must not be used in an air conditioning or refrigeration system. These fuel grade products contain high volatility and variable compositions and impurities. This will significantly reduce the reliability and performance, leading to premature failure and would result in:
Still not accepted in the USA to be used in automotive AC but other countries have approved it.

Dave, do you really think 134a will be dropped any time soon? There are what - 200 million cars with 134a systems? And, no retro options - at least practical ones.

Alright guys-
I did test the low pressure switch and by jumpering the switch the AC clutch and fans kicked on. So I guess I just have low refrigerant. Im not sure if I'm going to do the conversion to 134a quite yet prior to seeing if I can aquire either freeze 12 or R420a. Though I am curious.... How does one test the oil level in the compressor? Is there a dip stick? Will I lose any sort of pressure by removing the oil fill nut? And what do I not want to disconnect in order to not die from freon inhalation?
Also, where is the low pressure fill point on the compressor? Is it the one on the left, drivers side?

You can't buy happiness, but you can buy a DeLorean and that's sort of the same thing....
