Drain all the oil from the compressor, replace the receiver/dryer.
Insert new 134 compatible oil. Replace all disturbed O rings.
Charge with 134A .
Should work
Drain the r12 and put the 134 in. You can flush the system if you want to, but it really isn't needed. You will want to add some oil for the 134 in addition to the gas. You don't need to worry about changing O rings or anything else.
