WTB Help!!! Need to find interior rear quarter panels - gray for a 1990 Mustang GT hatch

I am trying to find replacements for my 1990 Mustang GT hatch interior rear quarter panels, but having a hard time finding them. Are these only able to be found at a junk yard?

I found a rear set on FB Marketplace for cheap. Currently there is another set being offered for free. Only downside for me is they are 4.5 hours away.
