Do the Sliderz mount to any particular side? On one slider there is an additional flat piece of metal welded to the flat piece that bolts to the truck. It's on the end and I currently have it installed at the back on the driver side. It does cause the back of the slider to noticeably stick out farther than the front. So...
Is this normal?
Why would it be on one slider and not the other? The other slider, passenger side, only sticks out slightly farther than the front and is probably caused by the fact that the flat piece that bolts to the frame overlaps a weld point in the back.

By the way, great job packaging those bad boys up.
