Yup, did so three days ago in my wife's '01 Sequoia, and a year ago in my '00 Tundra.

The Optima battery comes with spacer that fits under the bottom, which you'll need. When you receive it, it's the black cover that covers the top of the battery for shipping.

With the spacer underneath, it's still not quite tall enough; the hold down strap can be clamped down on one end, but not the other. So, you'll need
another spacer underneath the battery, or a small spacer underneath each end of the hold down strap.

I used 1/8 inch neophrene, two pieces each cut about 3/4 x 4 inches, under the ends of the hold down strap. Possibly you could find something appropriate at O'Reillys or Auto Zone.

Now, keep in mind that all this assumes the '07 is done the same way as the '99 - '06 models. I haven't seen it so I don't know, but it should be obvious that it's easy to get right. And, so far, it's been a very good battery in my truck. Both originals leaked, and these don't.
