Sounds about right
The regular Bronco was build on a F150 frame
I had one a few years ago, and added a 3rd row (from a Yukon XL, it had seat belts build in)
It was the only way I could fit the entire family in there...but that left about 2 inches of "trunk space"
The kids loved that truck, specially in the summer with the top off (it had a full size roll bar in it)
