ISO 1967 Radio opening

[Blue_Streak]

I have a '67 cab with the radio mounting tabs completely removed from the opening. I initially was thinking about fabricating new tabs with the correct hole locations and proper bends then I got thinking of an easier route.
So.... hoping to see if anyone out there has a wrecked cab or dash that has these tabs still attached. I was thinking that I would just cut out the whole opening ( from instrument bezel to glovebox opening ) and a bit wider than the radio opening , and weld in a proper donor piece. I know its probably a difficult find but just thought I would throw it out there.

I didn't know if I should put my request here or in the interior section so I put it in both.

Thanks
