I was wondering if anyone has any experience good or bad with the Rock Auto 4 season a/c lines.  I can't seem to find much info on them. I tried searching old threads but not much came up.
 
I'll be changing out my leaky heater core and since I also I have a new evaporator (both are gm new old stock), I figure I may as well do the evaporator while I'm at it. Since the system will be evacuated I was also wondering about the a/c lines.
 
The car has been converted to 134A. Should I even bother with lines? It's worked fine till now and I don't think there is anything wrong with them but for $95.00 I could put on new lines that I believe are for 134A refrigerant. It's one of those while your at it moments.
