Need info on proper towing procedure for a 93 Jag XJ6. It's listed in the service manual, but need a reference to a specific towing/service manual used by towing companies. I need this info ASAP if anyone can help. A tow company damaged the car by not towing it properly and I want to show documention showing proper industry standardtowing procedure.

Any help you can provide would be much appreciated.

Thanks much.
