Quote: Unless you're going for a spot on reproduction of the comp cars, I don't know that I'd want to copy the TA cages exactly. Even post 1970, the kit car program identified alterations that were improvements and a fair amount has been learned since then about about chassis rigidty and improvements. Looking at some of the pictures Barry put up, these cages appear to be pretty limited by the rule set of the day.
One of the biggest highlights in the ensuing years has been discovering the amount flex in the front third of the car and the need to have more rigidity in the firewall/A piller area and rocker area.
