My 2006 SCrew 5.5 box has plastic rail topper all around, covering front bed holes. Is there a way to install bed tool box without cutting/drilling through?

I have seen boxes which come with a clamping type of connector rather then drilling through the rail. The problem is that you better have it tight or your next quick stop at a red light will have your box sliding the length of the bed. I think I saw them at Pep Boys.

use j bolts, drill through your box but not the rails and then tighten the nuts

Thanks, z-pro. I think I have it now. Didn't get it until I looked and felt around the upper front corner of the bed. The hole in the box is inside the bed rail and the J hook grabs the upper inside lip of the bed rail. Sweet.
