Hey Bernie, the Robbins top although very nice, simply would not fit over a rollbar. They give you the piece of material from the back window with the top. I used that piece to make a crescent pocket over the hoop and a pocket over the rear brace. I had to make a set of roof bows with an adjustable hinge point to get them lining up with the seams and the right length. I have put a couple of them on now and they look and work great. If you are doing side curtains also start with fitting them and aligning your windshield to them before fitting the top.
