Yes, the fuselage is the same. So it fits perfectly.

Edit:
After posting this I went back to look at the C185 models that are available. I was wondering why I only have the two models painted with this scheme.

Well, I discovered that the "floats" version has a BUSH model. The amphibian doesn't. The bush model puts a window in the door panels. How cool is that. I want that in my amphib, and with the Misty 16 paint too.
Here is the result. Meet Misty 16B:
I've lost my wheels, because it's the float model, but because it's in the amphibian folder the wheels are just invisible. I can still roll down the tarmac just fine. I rarely see my wheels anyway. That's ok, I have a window in my doors now. Tada!!
(I have a twin otter amphib like this too (invisible wheels), with the fish skin on it)
