Here is what I found out....
The "retrofit kit" covers a recall:

So looks like if we had the tank recall done, it won't fit. But I wonder if the part can be modified. For $30 bucks, I just might try it as it looks like it snaps to the crash bar and then to the tank bolt. Maybe the small plastic retro fit tank mount interfers with the part snapping in place.
Oh well, will have to see.
