i was cleaning up the a/c lines for my challenger today and i noticed that they are a little rusty on the inside of the line.

now i took the lines off my car back in 94 and i didn't seal up the ends. now it's 09 and I'm putting them back on the car. I'm looking for the a/c to work and not have the lines on there for looks.

can the lines still be used? does something have to be done with them? or are they trash and should i look for others?

i know somebody will mention this,

yes the car in going through a full resto and i did replace EVERYTHING on the a/c system ,just not the lines.


thanks, Greg
