I wrote to Ford Performance and this is the "response" I got today....
I have asked about these hoop steps for you and Ford is looking to offer them in the future. I do not have a definitive answer for you yes or no, or timing. I would periodically check the Ford Accessories Site for this...
On Tuesday 11/09 I saw Cyber Orange Bronco driving through downtown Woodstock. I missed the trim level, I was actually watching the traffic in front of me.
I took some pics of the elastic strap the "Interior Parts Expert" at the dealership said goes from the back of the seat to the front, which requires the "Interior Parts Expert" to remove the seat.
It appears to me it only goes about 3-4 inches under the seat.
