UPDATED in response to post #4:
1. You can use Stainless Steel Pop Rivets (1/8"x1/4") every 12", to hold the BakFlip in place. That will eliminate the unsightly Clamps. This does make a permanent attachment of the rails. But the Cover can still be removed by taking off the 2 bolts and 2 rods. Pics added.
2. I know one fellow who trimmed the bottom edge of the BakFlip Rail, to allow clearance of the Utili-Trac Rails. He did not need to flip them then.
