May be aftermarket arms available, There are for the 03-07 rev chassis. Running boards are part of the tunnel assembly and are not replaceable. Some parts of the footwell area are available. You should be able to straighten it out if not bent too much. Then get the reinforcement pieces from Doo or Grip-n-Rip to stregthen things up a bit. Also check the lower arm mounting locations, they are a weak spot in a collision. There are brace kits for those too. I have all these things on mine. If you have insurance, they would likely total the sled if the frame needs to be replaced. A customer of mine hit a tree with an '05, rode it out of the woods, dealer wrote a $8000 estimate to replace everything damaged with new. He did not want to claim it because of other insurance issues. I repaired it for about $1600. That was 3 years and 4000 miles ago, never had any problems, and all the damage was properly repaired. Not bragging, just saying there are alternatives if you need them.
