A/C Changing from R12 to R134A Mulsanne S 1992

[Portamno]

Hi,

My Mulsanne S 92 is ALMOST ready to go, after 4 years of endless search for the right mechanic, here in Portugal....Now comes the issue of changing the gas on the A/C from R12 to R134....

I have searched the net, and on flying spares I have found a kit which provides 2 ounces of oil and the right plugs....HOWEVER, reading other related material it seems that the "drier" in the A/C system also needs to be replaced??

Can anyone offer a more complete description of what must be done?

THANK YOU
