Yep, I thought of the hard bikini top years ago when I tried using a normal bikini and it just kept pissing me off. A buddy wrecked his jeep and destroyed the hardtop. Lucky for me, he didn't bolt the front up and just the rear and sides were destroyed. So I have just the top section ready to cut to bikini size. I'm going to end it at the roll bar and use wide Velcro straps to wrap it around the bar while resting on two spacer blocks to position it at the correct height. I'm 99% sure I'll trim back the sides so it looks more like a reg bikini top and having the upper door seal looks kinda weird. But I don't know. I'll secure the front with the normal screws using the metal strip, or use thumb screws. I think anything more, like a plastic back or soft sides would not only over complicate things, but go against the idea of a hard bikini top in the first place... Well me me anyway.
