72 demon core support

I started taking my demon apart and found out that when the p.o. tried to move it he not only tore up the lower valance, but also the core support. It is messed up pretty bad on the bottom from the left framerail to the middle. Is it possible to change the core support? If so, how hard and does it have to be from a demon? I might be able to fix it, it will just take many hours as it is torn, twisted, and ripped from the frame. What would be my best option?
