As a final wrap up to this story, it turns out the warm weather (and a pair of vice grips) was my answer. The top is now on and installed correctly.
I was aware these tops were easier to install when it was warm outside, but I had no idea how much stretch they would have after being in the warm Texas sun. This probably would have been easier without the troop seats installed, but lesson learned.
Basically, this became a rinse-and-repeat process. Leave the truck in the sun, stretch; leave the truck in the sun again, stretch; leave the truck in the sun, and finally - Walla! The top fits now.
Copied from my earlier post, the side extensions connect to the rear of the b-pillar.
The sides then wrap underneath the seat belt. In my case, I didn't take off the head protection.
The top wraps around, but I'm my case, came up really short, and in the wrong position.
After a few days of cussing, followed by a few days of sunlight, stretch.
Cover routed underneath the seatbelt. Keep stretching.
Should be nice and tight around the pillar but keep stretching any ways. Also, the seam here is a big piece of Velcro, which can be released for more slack. Note that when installed correctly, the seam is parallel with both the troop seatbacks and the door frame.
After even more time, even more sun, and a pair vice grips, the cover should align. Note that this is the same turnbuckle that you started with originally, it actually used twice.
