NOS 70-up Dart quarter

You either bought the NOS quarter panel at a screaming deal (less than $500) or you paid something closer to $1k. Considering it's not a direct fit on your '69, which you likely knew before purchasing, you bought it knowing you could flip it and make some nice coin. There's nothing wrong with making some coin on a sale since an item is worth whatever someone is willing to pay. However, it sounds like you're asking for confirmation that you found a nice part at a great price and are now trying to ratchet up the selling price by suggesting to cut it up. If you're going to sell it, post it up in the classified section with a price and see if it sells. If it doesn't sell for the price you think it's worth, then cut it up.
