When that one flipped, the bar itself didn't fail, it was the mounting pad of the main hoop punching through the floor. Plus, it wasn't really a road-course bar, but a 4-point drag bar with no diagonal or horizontal harness bar.
Any road-course bar that will pass tech will also eliminate usage of the back seat at the same time... The diagonal runs from upper-left to lower-right of the main hoop, and there's a horizontal harness bar running across there as well. If you use the Autopower bar, you should reinforce the floor where it (or any other that bolts to the floorpan) lands the main hoop pads. A 3-sided steel bracket will be all that's required, with one plate on the floor, one on the rear seat pedestal, and the other on the rocker hump. Weld all three to the car and each other, and land the bar on that. John (Philostang) is doing up the extra bracing on mine.
The alternative is to have a custom bar made, and welded in. Either way, if it'll pass tech, it'll cost you the rear seat.
