chassis tube sizes
i've decided to remove steel floor pan and go all aluminum on floor;;i have 2"x3" boxed frame rails.14 point cage with some added bars of my own;;funny car cage added..i'm using m/s tubing on this build.i want to ceterify to 7;50's if possible;
i belive i need "x" bars between the frame rails[under trans tunnel area and a tube running diagonal from frame rails[2"x3" boxed]to rocker panels
what size would these bars need to be?do i need them?
