Actually the best way I have found to do it is the get as many bolts out as possible, then the ones you can not get out jack the tub up and cut the square plate that the bolt threads into out. This will be in a mount channel. After this is done drill through the floor of the jeep where you removed the "old square piece" and get carriage bolts to replace the old mounting bolts. You can use hex bolts if you do not want a more flush mount in the floor.
