I have a 75 H/O W-30, Great car 1 owner that I am trying to locate interior sail panels. These appear to be in low supply in the auto parts world, but I am still searching. If anyone can help me locate these panels it would be greatly appreciated. Robert

 

I see a pair for sale on ebay every once in a while.
I'll let you know if I find any around here.

 

Are you talking about the interior panels that fill the space between the package tray, headliner, and rear seat? If so, have you considered taking your car to an interior shop to have new ones manufactured? If you aren't restoring your car completely "original" this might be an option.

I see you are in OKC. There is a good interior shop in Lawton, OK. It's Cation's Nu Look. He did my door panels, both seats and package tray for about $1000. Top notch work!
