Can't measure mine right now, but two things: I don't think it's quite that 37" wide between the wheel wells, and second, depending on the type of flat panel, some of them do NOT like to be laid flat when moving it around. They've gotten better in this respect, but if it's a plasma, I would want to transport it upright. You might get the 66" if you move the front seats forward some, but it will be close. Hopefully, someone can actually measure. If I had to guess, my guess is no. Now, if you take it out of the box, it probably would fit as you'd lose a few inches all around.
I was able to get a 50" plasma standing up behind the front seats, so width across that way there was still some room on the ends, but you wouldn't get 66" there, either.
