Some of my lines on the 603 look like they are near the end of their service life. The outside coloring is completely grey and some are pitted. I was thinking of cleaning them up, but, it appears that serious consideration should be given to replacement. I take this vehicle several hundred miles at the drop of a hat.

What's the cost of a full set?

Dealer or aftermarket? Any quality issues or are the aftermarket lines made by somebody reliable?

I presume that you replace all the plastic clips at the same time.
