Well, those side pieces (left & right sides) are a lot cheaper than you think, about $150 shipped each. Mine have all (Left, right, and front) showed a little oxidation, so I bought a set for future installation when I'll need to. I had a tough time finding the front strip by the windshield, but they do sell that part separately also. The front part was about $180 shipped. You can search for better prices, shipping varies a lot between Parts sites.
The Left side (DP5Z-5451969-A) is about $150 shipped, which I got from Tasca Parts.
The right side (DP5Z-5451968-A) is about the same shipped, which I got from Ford Parts Giant. I only paid $75 for this one a while back.
The Front Strip (DP5Z-5451916-B) is about $180 shipped, which I got from Fairway Ford Parts.
These plastic parts get beat up by the sun, so they need a coat of wax way more often that the rest of the car. These parts pop right out and are easily installed.
