Looking for bumper extensions(?)

I am redoing my wife's 74 Maverick. I have found out the bumper extensions(I think that is what they are called) are rusted. Looking for some good ones. When someone does a bumper swap do you discard these? Where can I find some are they remade by anyone? HELP!!!

 

Bumper guards?

 

These are the square metal part that bolts to the frame then to the inner bumper..

 

Bumper Shocks. Front or Rear?

 

AWW that's what they are called makes since FRONT

 

Craig would be the closest one to you, that might have some..they are heavy and would be expensive to ship...
