Yes, the core support is spot welded to the inner fender wells. You will need to drill them out. there are about 30 of them. It really isn't that hard if you have a spot weld cutter for your drill. I swapped over a 4runner core support onto my pickup. It only took about an hour to drill out all of them. I just cut the doner core support from the inner fender wells and drilled out their spot welds from the other side on the workbench. Once your core support is off it is easier to straighten out the fender wells. Just take the diagonal measurements from the doner truck before you cut it to find out your goal distances. I had never done bodywork before and I think mine turned out ok.
