Anyway, I have a yellow top in the F150 that has made its way through my last three trucks. I got it in 06, never had a problem. I got it to support my 06 Explorer that I added a fridge, inverter, dvd and so on.
The problem of the optimas not filling your factory spot are easily solved. Its 1/8" steel and he will cut just about whatever pattern you want in the top, just make sure you tell him which way you want it orientedIf looks are important, and I have seen your hubby's FJ, looks are important, the optima with custom tray is the way to go. Here is a link to the dealer I used for the tray. As I said, it's definitely high quality, and he cuts the top for free within reason, so if he wanted "FJ" or some such, it would be no problemo.
