good question ron! I would not build a new cage with any 1"box because they have said that it wont be allowed as any part of a roll cage! you make your own mind up,and I will wait for more information,
Thanks Mick....agreed, I wouldn't build a new cage but as I am already running 1" box.....as the rule change isn't planned to be in force until the start of 2015, I'll put the angle grinder on ice ....... at least until the 2014 rule book comes out and it says otherwise. Thanks, Mickey
