Customs Question for Muntz (sters)

While restoring my '51 Muntz I keep across things I don't know where or for what their purpose is. Anyone know where these brackets belong/purpose? Thanks

 

There is a neat face book page for Kurtis cars. Mr. Kurtis was the designer of your car so you might get some help there.

Thank you. I'll check it.

Looks like the one on the left goes on the right. Other than that, not much help.

 

Hmm... Don’t recognize them. How big are they? Need something in the picture for scale.
