Hack Alert beware

That's probably enough to get law enforcement involved in. In most states, that would be considered a hazard to others on the road. I know in Georgia for example, when a car is repaired after being bought back from the insurance company from a total, it must be inspected by The Georgia Bureau Of Investigations before it can be road worthy again. Seems like this kinda thing would fall under similar laws in your state. If you are able to do so, I would sue to have them provide new frame rails PLUS installation funds to have them installed CORRECTLY by a shop of your choosing.
