Thanks to Kenp for the wind deflector removal. That is half the solution...

The light bar has front stops, that prevent it from going further forward. No idea how to remove these front stops. The front stop is labelled "Onstar Antenna Stop". Presumably to avoide interference with the Onstar antenna if the roofrack was too close.

I really do not give a hoot about Onstar, because all it is, is a built-in cellphone. Dumbest feature ever, and totally useless. The only time I needed it during an accident, it failed since the location did not have cell phone reception. (For those of you who don't know, onstar works off cell phone service, NOT satellite). No cell, no onstar.

So how do I remove the stops and move the light bar forward? The stops are anchored somehow underneath the roofrack rail.

Anyone out there with a Special Edition H2 that has done this mod?
