I’m in the middle of doing my son,s 90. I didn’t go with the Battle boxes though. I decided to make my own.
It’s not that bad it just takes patients and time. With the Battle Boxes the hardest part I could see is to get them into the opening. Once they are in there, it’s just a matter of drilling the holes and installing the backing plate on the inside of the Mustang. Make sure you bend everything back into place and weld up cracks
I cut open the torque boxes to gain access to the inside of the box. Then a plate was added to the inside mounting surface of the box that runs forward to the sub frames. I then added plates to the forward and aft part of the torque boxes along with the floor of the boxes. Everything was welded together. Cost me $30.00 and time. It is a whole lot stronger then the Battle boxes. Not that they are bad. I just like to make my own stuff.
