Can someone tell me what this body part is called and can I find new ones online?

It’s a support brace for the rear quarter panel. I need to remove them to replace the floor.

Both of mine are pretty rusted out.

 

It's a rear inner quarter panel to floor brace, and as far as I can tell they aren't even reproduced for Chevelles. Fortunately it is completely hidden when the car is assembled, and it's pretty much bent up flat sheet stock.

 

Thank you, at least if I butcher it up you won't be able to see it.

 

Just saw these on FB marketplace.
