It may be OK, but if it is cracked they can still bend easily. I can send you a scan of all the rail dimensions to check, but you'll have to pull it apart to check it. Looks nice a nice ute, why not buy it and change the rails? You'll have to pull the whole front off anyway and the engine has probably broken its mounts anyway. If you can get access to a 2 pole hoist you could fully refurb a replacement chassis and slide it under that shell in a few hours on a hoist.
