KE70 Rear Bumper

[bkh808]

Just wondering I have the big bumper on my Corolla but have a chrome rear bumper ive been wanting to put on. Is it true the KE70 that came with the chrome bumpers don't have the big holes like in the picture below?

I want to use these brackets and weld the big hole up and drill new ones. Would those 4 bolts be enough support to hold the bumper up?
