There is an easier solution than a retrofit.  R-406a is compatible with
R-12 and the mineral oil, and is a little more efficient due to the fact
that it's a blend of refrigerants.  ie it works a little better than
R-12, whereas R-134a works a little worse.  It sells under trade names
Chillit and Autofrost.  See www.autofrost.com.  You don't have to change
oil, o-rings, or anything else.  You can even mix it with R-12, but if
you're in the USA and the EPA catches you, they'll cut your weiner off. 
Been using it for over a year w/no problems.
