Hey guys,
  So i got the kick back in the shop since i'm on vacation and i'm building new front bumper almost done will be by friday. Any way i think i'm goin to start on a roll cage and i've got some round tubing in the back i'm not sure what size will be heavy anuff for the cage. anybody got any ideas.

I use the 1.5" dcom on my SJ, not sure the gauge though.  The Petroworks Sports Cage uses 2â€? x 0.120â€? for the main hoop and 1.5" x 0.125" for the rest.  You can see the review at the gear guide located at http://www.zukiworld.com/month_120108/feature_gear-guide-petroworks-sidekick-roll-cage.htm

i've seen petoworks and though about buying it, but whats the fun in that i love to fab haha thats what my sidekick is and done very clean plus i dont have 650 plus shipping to spend on one i'm a budget guy got all kinds of ideas, and a bunch of note books with designs for parts. just real slow going, but the petoworks is real simialer to the one i have drawn out i just did more gusseting like sipder webs to make it look cool.
