The fact that you have a set of nice panels is something worth valuing...highly. Any color, other than black, will probably be seeriously degraded/chalky after this time, so your chances of getting white panels is highly unlikely.
Rear panels have the same basic location for power and crank window, so don't worry about that.

Metro panels will most likely never come out. Any who were interested were told to provide a credit card number, name and address to show we were serious and they never got to their desired quantity.

I would not buy aftermarket, unless the car was a daily driver.
I would not have Just Dashes recover them either, but that's just me.
I paid dearly for a black set and dyed/painted them (blue) and they are OK, but it doesn't take much to take off that thin coat of paint and this type of plastic doesn't take paint well. But, it looks more stock.

Door panels and seat backs are awesome from Metro.

Hope that helps..a little.
