[DeTomaso] 1972 GUMBALL PANTERA AIR CONDITIONING

[LEVITT1946 at aol.com]

Dear All,
 
I need to refill my air conditioning system. The system was disconnected  
while in restoration. In 2009 The Space City Pantera Club refilled my  system 
with FREEZE 12 and the system worked well. I would prefer to put in R12  if 
possible instead of converting to R134. I have been told that if I convert 
to  R134 the system will only work at about 85%. If I fill with R12 the 
system will  work at 100%. 
 
I need to replace the drier as it is an antique. Anyone have a part # for  
the drier?  The compressor has been updated from the original.
 
Does anyone know how much refrigerant oil goes into the system and how much 
 R12 the system can hold?
 
I have checked craigslist and there seems to be a lot of people selling  
original cans but I am not sure how much to buy.
