My neighbour had the same problem and found the bracket to attach to the car cost very big money from Holdens (from memory it was over $1000)....plus if you have an airbag (as my neighbour had) you must use the approved attaching brackets that are airbag compliant. Crap I know, but if you weld them solid and hit a roo there is a good chance the airbag will go off.
