Here's the Gobi Stealth rack modified to be an Ultra Stealth rack. I'll eventually get the wind deflector put on, but need to modify it a bit to account for my GPS puck.
The clearance between the bottom of the rack and top of the roof (at its highest point in the middle) is about 7/8 of an inch. I contemplated fabbing shorter brackets, since the 2" that come with the stealth are the shortest that Gobi makes; but Gobi pointed out that the rack will bend under full load and the 7/8" clearance is there to compensate for that flex.
The rack is a bit taller than the H2 roof handles that I was rocking, but shorter than the OEM crossbars...mission accomplished in my book. I can throw a piece of plywood on my truck and still fit in them fancy 'big city' parkin' garages...lol.
