This is the setup I use- like this- If you lucky the studs will back out with the Lock Nuts, if not jump underneath and use a pair of mulitgrips/long nose pliers (I use vice grip LN-6 locking long nose pliers) to remove the studs. You bork the thread in the process but if you BA turbo has been on as long the stock bracket still being would indicate, they are due to be replacement anyway and are cheap ($40ish From Sonice Performance/MTQ)
