I added the tabs and I also added the razorback/antenna mount on my 5. Basically the aluminum angle that was the turtle deck original attachment point will be used to cover the new mounting tabs and the fabric will go over it. Really wasn't a whole lot of extra work if you don't mind welding a little. I don't know about just using hysol to hold tabs on. Maybe a bracket wrapped around the tubing and glued, but just gluing tabs to the tubing....not sure that would hold especially if you fly with the doors open.
