I received the end clamps but not the middle clamps. It sounds like you are saying the middle clamps will slide into the superstrut. The end clamps won't as that piece is wrong.

Do you recall what those pieces are at lowe's or amazon, etc? I just need to find them to order them.

Ask a hundred busnuts how they attached solar panels, and you'll get a hundred wildly different answers, and if you're lucky some of them will be sensible! FWIW I drilled through each roof rib and inserted 3/8" stainless socket-head cap screws up from underneath, with stainless NyLok nuts on top to hold everything securely. When I insulate and cover my ceiling all the holes in it will be covered.

I'm certainly going to come up with my own solution as well. But i'll be documenting it with in depth pictures and instructions.

I used this rack from Amazon, I liked it because i angled the brackets to match the curvature of the roof, I did not use the screws they provide, I used SS bolts in to the hat channel flanges. https://amzn.to/3QzULag

3M tape

I used two sided tape on L-brackets. 3-M tape. I had AM Solar in Oregon design. When I saw that it was just what I called sticky tape I was pretty leery but they said it holds.
On the bottom edge where the roof curves a lot I added one screw to each bracket in addition.
The first few trips I kept stopping and checking as I couldnít believe it could handle the winds and side winds across Wyoming but all good.
Three years and lots of miles no problems.
Let me know if you want a pic.
Cheers!

VHB tape (or whatever you used) is only as secure as the paint it's stuck onto.

Be careful with relying on the cheaper hardware (bolts, etc) If they originated in China, you might have bought what you thought was Grade 8 but, for some builders, they could end up being Grade 3. Check out Chuck Cassadyís YouTube video about the trailer that snapped off his hitch. He can steer you to a better brand if you need it. Good luck with your solar.

I tried these u bolts. They went in nicely but weren't long enough. The longer ones are too wide on mcmastercarr.

Where else might I get some ubolts that will fit around the ribs of the roof?

Solar roof mount

If you can only fit 5 panels increase the power of the panel and just use four panels. They now have panels up to 600 watts.
