yes. The new bags have an additional top strap to allow them to mount to the top bar of the top rather than the hoop.You are good to go sir.
It also should clear the antenna you have mounted as well. But without seeing it in person I can't say 100% for sure.
That was the first thing I had to do when I got the top put on...I Had to find a couple of heavy duty Velcro straps and loop the Meansling bag Velcro through then and then the other piece around the bar of the top. Minor inconvenience for a great product when it comes to a first gen product. These are still my favorite travel bags for long weekends, with or with out the slingshot.
