The racks would likely work if the top hole aligns with the sport top bolt. Also the top bracket hole could be repositioned to match up with the sport top bolt shown in the pic. I think it could work. The rack bracket that goes on the front of the hoop is recessed inside the hoop so it would not appear to interfere with the top bracket. You would need to cinch it down with a nut on a bolt long enough to go through the top bracket, then a 2nd nut for the top bracket.
If you think this would work, I could always send you a set and if it works, pay me for it later. If it doesn't, I would pay to have it shipped to the next buyer. I'm back off to my project now, back after 5:00 west coast time.
