If memory serves me right, I think that when I measured that, I went by the distance WITHOUT the contours on the hood, and as if it was a straight measurement. I think at the time, I chose to not confuse people wanting to do this, and show the measurement as a "straight-on" version.
That would explain the (short; 5") difference in measurement.
Anyway, glad to see that it's been fixed. Thanks!
BTW--remember that the cut metal on the underside is exposed--as these were cut at the factory after the hood had been painted. Another thing to look for when buying an "original" GT/CS.
