Ah your wife doesn't understand you either...........I'm glad to see Aussie has finally done away with alloy cages they've been illegal in NZ for over 10 yrs. I have seen alloy cages snap and do some really nasty damage to the occupants. When I do a cage I make the front legs in 2 pieces and join them down the windscreen pillar. With a tube inside and some plug welds as well as around the joins. I can then twist the 2 pieces to get the tightest fit in the footwell and roofline. Are you allowed to do that in OZ?? Where the join is on the pillar I also tag it to the body. It sure makes life easier than trying to bend tube in 2 different planes...
