question about the radiator support core

is the radiator support that the radiator bolts to and the headlights go through welded to the other parts on the side or is it bolted somewhere. i can't figure out how I would get it apart but i need to replace it. got in a front end collision and took apart and ordered new bumper, valance, driver side fender, radiator, grille etc, but after taking all of that apart found that the radiator support was all bent up on the drivers side about where the headlight goes through and a little on the lower center, attached is a a fuzzy cell phone picture. just wondering if I can somehow take this apart myself with my limited tools or if i'll need to get a shop to weld it in for me. oh yeah the section that is under the fender is also twisted a little but I think i can get that to work with a little pounding.

 

I just bought a 98 tacoma that had been wrecked. I had to replace the front end and straigtin the frame( no fun). the core support welds in on the inner fenders in several places, behind the corner markes(vertically) and under the head light(horizontally) where the inner fender and core support touch. If the truck has been wrecked before, like mine, you may find more welds. You can start by drilling the spot welds or by taking a chisel and hammer to the welds. when reinstalling you dont have to weld it all back together but it will make the front end alot stronger, as from the factory.
