I just had the windows filled in in my HX and I supplied 2 complete side panels which were fully welded in.
Ill try and get some pics up soon as it is at the panel shop and I only pop in once a week. Last I was there both sides were replaced, the passenger side completed and the drivers side in bare metal still.
As for value I'm not sure. Like anything it's only worth what someone is willing to pay you for it.

Cheers.

Gaddy.
