Type85 AC converions to R134a & receiver dryer & envirosafe

[Ben Swann]

Where does one procure the receiver dryers economically - can these be obtained as a generic component from FLAPS?  If they are not totally crudded up and rusty, can they be "rejuvinated" at least to a degree, perhaps using solvent or heat.   I need to do several of these systems and need a cheap source.    Hopefully the answer to my first ? will make question #2 irrelelevant.

I concur with the recommendation to use Enviro-safe.  It has worked well on a few I've done already, even taking some shortcuts, like not replacing the R/D, but plan to do this on the other systems.  The Envirosafe cools comparably to R12, and in my experience better success than the R134a, cheaper too(by the case).
