How move rooflight light bar forward?

Thanks to all you guys!

It worked. Job done. The light bar does NOT interfere with the xm antenna, which remains just ahead of the bar.

The wind deflector is a pain, as it is about 1/4" too high. I have squashed it under the light bar. Add a small rubber bumber to the contact point(s), or it will scratch the wind deflector. The outer wind deflector corners lift about 1/16" on my rig due to the pressure on the wind deflector center top from the lightbar. Will monitor to see if this is a problem, or if they warp back down.

Looks a lot nicer with lighbar moved forward.

Caution: Look out for pigtail and zippywrap it so it does not flutter in wind and scratch your roof paint.

Here is how to remove the roofrail stop. This was hard to figure out:
1. Squeeze together and lift the part of the stop that is inside the goove of the roofrail. It is rubber, so no chance of breakage.
2. Pull out of groove and bend towards centerline of vehicle. Bend the snot out of it.
3. Now, the other end is wedged under the medial part of the roofrail. Forcefully push DOWN on this part. It is hooked under the roofrail. It will pop down and release. Do NOT use a screwdriver or other sharp object to help do this. You can scratch your roof as it abruptly pops out.
4. Done. Easy once you know how.
5. Clip stop back onto some other part of roof rail by reversing this procedure, so it does not disappear in your garage.
