Wasn't there a company out there that was reproducing OEM style brake hard lines with the rock guard for our cars, or at least the L-bodies?

I've been replacing the original brake hoses on my new GLH and I've already snapped one of the hard lines due to the flare nut seizing to the tube. I have a bad feeling this is going to keep happening as I progress on this project no matter how much I douse everything with PB Blaster..
