issue with AMD Demon floor pan..please help newbie

any help is not foolish. yes i have tried that and it does work but it takes a lot of force to do so, but i think it should work as long as when its welded it doesnt pop off lol.. right now the big issue i have is with the sides of the hump the gap there is about 1 inch and i dont see how it can be pushed in.
Are their any holes that you might be able to draw it in slowly with a bolt and a large washer as not to pull through the pan...
