the 93 has 134 factory, the 91 has 12
the condensers look identical. not parallel flow or anything...
is the compressor different?
I'd like to upgrade... is upgrade a good word? the 91 a/c to the 93's 134a setup. I'm thinking swap the hoses, compressor and condenser... and put in a new txv... and of course dryer etc.
smart?
