Looking excellent Jeff! This makes me anxious to get mine going.
Question: are you using the OEM plastic strip to hold the bottom of the panels in the belt rail at the tub, or some other method?
Yes, there's a plastic strip on the bottom of the panels just like the on the OEM soft top.
Also, how are you keeping the forward edge of the side panels in the door surround without tension from the panel when it is rolled up?
I'm not sure I understand the question, but I'll explain how the front of the side curtains work, maybe that will answer it.
There's a "zipper strip" attached to the back of the door surround. That's got a zipper and a velcro flap on it. The side curtain, when rolled down, is zipped along its front edge to that zipper strip, and then the velcro flap seals over the zipper joint.
When the side curtains are rolled up, that zipper strip is still attached to the back of the door surround. To keep the zipper strip from flapping in the breeze when the sides are rolled up (or removed), the zipper strip is secured to the vertical part of the roll bar with two velcro straps.
Did that answer the question?
BTW there's a similar zipper strip running under the drip rail, which the side panels attach to. By undoing that zipper, the entire side panel can be removed, if you'd prefer that to rolling it up.
When the side panel is removed, it can be rolled up and stored above the side bars of the roll bar (so in almost the same place as they are in the rolled up photo I posted, except they'd be inside the roof sitting on top of the roll bar). The same snap straps that hold the side curtain in its rolled up position also serve to secure the removed/rolled up side curtain above the roll bar.
