Now I get it. That change to the tray was something I remember reading about but since I couldn't put my finger on it as an item to consider, I omitted its reference.
What I posted from known vendors was an attempt to highlight what's available. A WYSIWYG issue. Then the only difference is the strap that attaches to the corner. I posted, "Fabrication may be necessary" to suggest what may be needed. As you can see from my photos, I'm making do with a mismatch of parts (I will confess, a couple of needed bends in my strap was a surprise). As posted by Randy, he fabricated a look alike.
I think you could take the two and find a local welder to create what doesn't exist.
I have a short list of jeep parts that had to be made from scratch because they simply don't exist. Since I've taken so long to get mine back together, I've noticed that over time some of those missing pieces (that I took the time to make) have now been added to some of the vendor's inventory.
To me, this boils down to two scenarios: If you want it now - make it. If you're not in a hurry, perhaps over time, one of the vendors will offer that part that isn't available now.
I'm not a welder, so I farm that type work out. I've been fortunate that I have two shops locally that I've gotten to help me with all sorts of things. Hope this helps you with mapping out a plan.
BTW, this thread may get me down to one of those shops, in the near future, to alter my hold down to mirror what we've been illustrating.
