1966 D/Dart

Looks like my old D/Dart is going back up on the Mecum Auction block this Saturday, October 3rd. Any guesses as to what it might bring? It looks as though they put a set of ceramic coated headers on it and set of small bolt pattern Cragar S/S mags. The last time it was on the block the bidding stalled at $40K. My guess is $47K.
