73-87 Cab Corner and Heater Box

[GonicGM]

I'm looking for a passenger side OEM inner cab corner for 73-87 Chevy or GMC pickup. If not the majority of it, I would settle for the inboard vertical feature adjacent to the fuel tank. This feature is not included with any repro. I will provide image. Anyone got a junk cab around they can cut this off for me for $?

Also looking for very clean original steel non-A/C heater blower motor housing, engine bay side.

Got the cab corner feature. Just looking for the heater part now.
