It's my understanding that you can only purchase R-12 if you have a certified
A/C mechanics license. And if you can find any to buy, it's really expensive;
like $25 per pound.

>Chris,
>You have 2 options when rebuilding the dash air. You can convert to the newer
freon ?R134 or stay with the R12 freon. I chose to stay with the original R12.
>Both have advantage and disavantges. With either you need to replace the hoses
and all o-ring in the system along with the dryer. The hoses are available from
Golby or you can take your old hoses to a Good AC shop and they can replace the
rubber parts and reuse the metal ends. The dryer is available at most AC shops.
I got mine from Buskirks. The hose selection will be determined by which freon
that you decide to use. Also make sure the the rest of the system is flushed
with acetone and dryed. This gets all the dirt and junk out of the system. You
may have to replace the expansion valve if the system was really dirty. I am
sure that other netter have gone thru this experience. The cost is not cheap,
but the result can be COOL! If you have the earlier(Before 77) AC there are
several Mods that can be done to increase the capacity and allow additional
cooling. I am sure that Emery can help in the mods.
