Any one have any close up pictures of the factory inside cab corner reinforcements on a 1960 4x4?

I am thinking of buying a 60 F100 4x4 and use to have some pictures of these reinforcements-but have misplaced them.

I want to verify that the truck is a real factory 4x4. It is my understanding that these reinforcements and the GVWR are the only way to tell a factory 60 F100 4x4.5000 GVWR are base/non DSO 4x2s and 5600 GVWR are 4x4s.

Is there other things to look for in a factory 60 F100 4x4? Sure are a lot of 110 inch wheel base "factory 4x4"s out there-and I know better than that . And I think that Mr ND has stated that all factory 4x4 have horn buttons and not horn rings.Even the 4x4 Custom Cabs.
