Freeze 12 A/C recharge kit \ A/C question

[sukchew at suddenlink.net (Chuck Blue)]

   Freeze-12 is 20%142b and 80%134a. There are several types of R-12 
substitutes that contain several types of refrigerants such as 22,  124 , 
142, 134 ,Butane and various other things.If freeze 12 is 80% R134 why not 
go ahead and convert to R134.I have seen several conversions that have 
consisted of changing the fittings running a vacuum and putting in 134.They 
seem to be working okay.You might have to play with the charge amounts 
some.I think that you should only charge 80% of the R-12 charge amounts.
   Good luck
