I have both but I did a custom fit.
The loops are purely for show and bought from a former member of this parish who failed to supply fixings, and then blamed his daughter! I bought some bolts that fit the threaded holes on the underside and some thick 2 inch square spreader plates. I cut foam out from the underside of the T-bar to accomodate the plates and bolted the loops to them.
The clear windbreak (from the same source) uses glass shelf brackets, these I have screwed through the T-bar into the mounts for the tonneau cover that I never use.
Mike Satur sells hoops and windbreaks.
