Anyone installed a simple roll bar for frame stiffening/safety in their convertible?

I installed a four-point rollbar in my '68 Barracuda. It has the complete US Cartool chassis stiffening kit in it too. The middle support bars attach to a plate that's welded above the frame,many those bars pass between the upper seat back and the bottom seat cushion near where the seat belts pass through. I didn't have to cut any of the interior except where the main loop goes through the carpet.

These upgrades transformed the car from what it once was. Fortunately, I started with a nearly rust free garage kept car. I also made a strut tower brace. It needs to be changed slightly, because I used to have a /6 in the car when I made the brace, and now it hits the A/C compressor on my 2001 5.9 swap. That motor has been upgraded to an OBDII 408 Magnum, so the car is really benefiting from the increased chassis rigidity.

I'll post a few pis of the rollbar as soon as I get them.

Here are some pics...
