U-bracket for WD bars ... issue with self tapping screws

Path,
Just in case you or someone else has not seen it, we have an excellent sticky thread on setting up the WD hitch here. It will take you, step by step, with many additional links to other relevant sites, on setting up your hitch. It also has some good photos and tips on some sway control devices (mostly friction and Dual Cam).

Incidentally, just because somebody at E-trailer says something does not make it gospel.:W
