And just to throw a monkey wrench in; 3.23 chunks are cheap. You could buy one and stick it in, then sell the 4.56er, and probably do better than break-even.
That's what I did. Changed out my 3.55 in my Dart for a 2.94. Found a good complete center section, swapped them out and made $100 in the process after selling the 3.55.
