Doug,
The only other fsx C185 I'm aware of is the Abacus Premier Collection C185. Though the panel layout is more to your liking, the aircraft lacks the detail and models of the Carenado. You can see it or download a 7 day trial here.
http://www.abacuspub.com/fsd/catalog/s582.htmOn the off chance you're not aware, in the Carenado there are a couple of ways to see things hidden by the yoke;
-hide either yoke by clicking on the 'hot spot' located in/near the yoke tube bushing.
-or open most any gauge in a pop-up by clicking the 'hot spot' on the gauge face.
I have modified the panel, replacing the 300A Navomatic with the default Bendix AP and DME in all panels. I also swapped gauge positions in the Tundra to see if it might work for you. Here's a couple of images.


If you're interested I can send you instructions or the modified panel.cfg files.

At that time [1909] the chief engineer was almost always the chief test pilot as well. That had the fortunate result of eliminating poor engineering early in aviation.
