since I don't have a non sunroof model I am removing the sunroof and filling the hole. after removing the assembly I drove the fj with nothing in it and the roof started oil caning and bouncing hitting the roof support cross member and this was just on a slightly bumpy paved road. question what have other members done to reinforce the area. will just filling the hole cure it or do I need to add a roof support cross member. will just putting the gutted sunroof card back in stiffen it back up.. for sure not putting the sunroof back in . I can't be the 1st one to do this so hoping someone who has done this pipes in or shows me an old thread that covers the options and ideas. looks will not be my big concern as this is just an adventure rig not a daily driver show piece.
