Made a few changes recently, I decided to cut off the exo and add an internal cage instead, and then I decided to cut all of the body off behind the front seats...
I used a pro tools bender for the job, 1 3/4" .120 HREW for the cage. Then I cut off my sliders and made new ones from 2x3 .250 square tube(the old ones were REALLY smashed up)
I ended the cage at the crossmember in between the tires, as this winter I will be linking the rear with air shocks, and the front will be coilovers. I figured this way when it gets linked I won't have to re-work the cage and I won't have any frame overhang when I am done.
here's another from the rear, I am really happy with how it works, suprisingly it isn't too bad with such low weight over the rear springs, it definately flexes much less but it is very predictable.
