This happened to my buddy's wife as well. She's the same hight...he bought it as a surprise for her. Unfortunately, the surprise was on him when he realized that she couldn't see over the dash. Having already brought it home from the dealer, he couldn't take it back (not sure that he wanted to anyway). But I think Toyota should build a little more adjustability into the ride height of the FJ. Otherwise, I'd try to get a fabricator to make a "booster bracket" that can be mounted under the seat. Let us know what works for you and I'll be sure to pass the info along to my buddy.
