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

I installed a 4-point roll bar on my 67 cuda convertible. We tied it into some perches welded outboard of the sub-frame connectors. It gave me a good anchor point for shoulder-belts. Also bolted a piece of steel pipe across the front below the radiator support at the front of the frame rails. Car was much more solid-feeling, and ride was a lot softer with the road surface roughness being handled by the shocks rather than by chassis flex.

I was wondering how this fit, and what mods you had to do to the rear seat or the top well. I can't see how it would fit without cutting up the rare rear side panels.

I could see if you wanted the stiffening and didn't want to change the looks (and weren't concerned about rollovers), you might go with subframe connectors and a hoop inside the trunk behind the top well. The rad support brace is a good idea. A shock tower brace is another idea, though that's not a major flex point on Mopars. I've also heard of under cowl hoops, though there is a lot of stuff in there already.
