In teardown, I'm evaluating the places I need to replace parts or patch. Front fenders are off, leaving the firewall exposed.

On the driver's side, there looks to be a separate bracket bolted in,which extends from the cowl inner panel down to the toe panel; and the inner fender bolts to this. What is this bracket called?

Is there supposed to be a similar piece on the passenger side?

Looks like maybe mine was rusted out, and the PO just welded things together. Anyone know where I can find a new one, or what it's called so I know what to ask for?

Thanks,
mark.
