Not too hard to add/change lines yourself. No need to pay a professional for jobs one can do themselves. Save the professionals for things one can't do....like paint and bodywork.
If we left everything to the "professionals" nothing would ever get done. And none of us would be here talking about this stuff. Not everyone's got the money to let the "professionals" do it. The lines I have on the Comet came from a wrecked 93 E150 van that a friend's kid rolled over and we stripped for parts. Stainless steel lines, with rubber between the cooler and transmission cooler in the radiator. No leaks. No professionals.
