[DeTomaso] roll bar

[Mad Dog Antenucci]

I don't agree with Jacks comment that "about any roll bar will work..." 
  Dick Drenske is the expert here that I would rely on but I'd agree if I am going for a off-road excursion bent is better then broken  which is why I had Drenske replace my chrome moly cage with mild steel. I've seen roll bars and cages that also were not secured to backing plates or reinforced.

  Not to be maudlin, but a broken piece of steel tubing ( suspension arm I
think ) is what killed Aryton Senna, allegedly piercing his helmet, some
talk of a conspiracy about when he really died, common thought is that it
was instant but covered up so as not to make the announcement that same
day. Maybe not true but that is what I have always heard.

I think I'd take bent before I'd take broken, Racer Ka Bob doesn't sound so
good.
