Yep, it's going to be a street car so we'll need air conditioning! Aaron Strope has converted over all the a/c system's o-rings to HNBR o-rings to convert Magnum TPI over to R-134a refrigerant. The R-134a molecule is smaller than the old R-12 molecule, so old R-12 o-rings tend to let R-134a refrigerant leak past them. Also, R-134a causes the older o-ring seals to swell and deteriorate. Note that special R-134a quick disconnect adapters were also required for the conversion. At this point, Aaron is evacuating the system to check for leaks and to evaporate any condensation in the system.
