How much is a Rear window defrost system worth?

There is also no grille when installed in a 70 Dart either, just the perforated speaker openings in the package tray.. It is a shame that someone was so lazy that they cut the switch wires instead of pulling the sill plates and taking the whole wire bundle out. If it all works and I wanted one I wouldn't balk at $100-125 - it looks to be in good shape and wouldn't need much if any restoration. I bought a 70 Dart with one of these in it and was so tickled with how well it worked that I have installed one in both my other Darts. if you buy it and need pics of the wiring, connectors and routing let me know - I might even have one of those wiring runs.
