Your best bet is Cleveland Pick A Part. The items you are looking for are common items and not normally swapped out for better or aftermarket parts. The only people that might have what you are looking for are people that have done complete custom modifications to their interior and even then the pieces that they removed to make room for the new ones probably have been Frankenstiened and chopped up to work with the new stuff they installed.
Like i said your best bet is a salvage yard like Pick a Part or something similar.
I hate those sites, lol, never know what they hell they actually call those panels I need, and the sketches suck. No thanks on the tri-fold, it's in decent shape.
