One thing that's been overlooked in the conversation is since you have only a 8 point roll bar ,you are limited to to a combination that falls into SSGT/E or F ,and then only if you run the index . Even dropping to a lower class will need a cage if you run under the index.
Most viable combinations that can fit the car most likely will need a roll cage .
Before jumping into the "shark pool" ,visit a Lucas Oil Divisional race and seek out some racers that are running Mopars in SS .
Most will at least tell you what may not be a good combo and more than a few will at least steer you in the right direction.
