Under no circumstances should you put r134a in a system that had r12 in it unless you can purge the entire system of whatever oil (mineral oil, most likely) may be in it. The r134a oil (POE) will form globs when it mixes with the mineral oil and plug up your cap tube. I can't even imagine what your install cost would be. Around here I charge $1500 parts and labor for an r12 heart/lung transplant and I guarantee it for 3 years.
