Door Panel Nut Replacement

[68mg]

I'm replacing some of the interior door panel nuts on my 69 C20 that were rusted out. I have the correct replacements and have replaced all of them except the one nearest the hinge since it's enclosed by sheetmetal behind it. I'm wondering if anyone has been successful replacing this nut or is welding a nut or using a plastic/nylon license plate nut insert about the only good options? Since I have the correct replacements it would be nice to use them.

Welding a nut in or using a license plate insert were discussed in this thread:
