In the Book 'Shelby GT40' by Dave Friedman on pages 118/119 there are three pics post the crash test that give an indication of the cage design.

FWIW, the removable bar as in Deanes Cage is one element of the cage that I would like to see deleted from cars with a relatively narrow cockpit, there have been too many fatals and severe injury incidents from 'that' bar where the car suffers a side impact as a result of a crash or even sliding sideways off the track into a barrier etc . The cage in the Daytona that Peter Brock ( Aust) died in is an example of this. ' That' bar was only inches from the side of the helmet in what is the weakest point of helmet design. When you get the sideways whiplash effect from a slide into a barrier or from a car slamming into yours if you have spun/stalled on the track the Best Hans Device or full harness in the world will not prevent your Head/Helmet from contacting the bar. This applies to most of the cars being constructed by forum members & I feel that it is time some of you who may be in a position to influence the Rule Makers in your various sanctioning bodies to have a serious look at changing the requirements in this area.
