After all rivets were cut/sheared off I sawzalled down the sides and the middle of the crossmember.
However event with all rivets on both sides cut and off ....... couldnt get it apart. Punch didnt do much at all ........ so basically ended up using pickle fork and various claw hammers around it to eventually pry it off.
Not an easy task at all - in fact the rivets heads really werent that bad with right tool - but getting it off was a bear.
