Some may disagree, but this is MHO. A vehicle designed for R-12 needs to remain R-12. To use 134 the A/C condenser needs to have AT LEAST a 25% larger capacity to properly cool. 134 runs at higher pressures & the original hoses were NOT designed to hold these kind of pressures. Also you need the newer hoses which are NOT as porous as the orugunals. Lastly, the original A/C compressor was NOT designed to cycle on & off. All the O-rings need to be changed along with the compressor seals as well as the receiver/drier. I know some have converted to 134 & had great results, but I REFUSE to do this in my shop.
Again, just MHO.
