DOT 5 can be used if all of the old fluid is flushed out first. DOT 5 SHOULD be used if the car is in a damp climate and tends to sit around a lot in between good long runs on the highway. Otherwise you will be throwing away rare, expensive, and otherwise good parts ruined by accumulating moisture in the system.
