Need help identifying this power steering conversion

[1Ratty64]

So i need a little help here because i haven't seen one like this before. All of the power steering conversions i've ran across require the steering shaft to be shortened, but yet mine isn't. The steering box setup is about the only thing i haven't changed since i picked up the truck and i'm kind of at a loss. You can see how low the box sits in the front and i actually get occasional sway bar contact with it. The drag link is perfectly level and completely centered....it is extremely close to the engine crossmember but doesn't contact anywhere in travel. No problems with alignment, driving etc..etc..etc...Just wondering if any of you guys recognize the conversion bracket & frame stiffener used and can maybe shine some light on what pitman arm was used and if this box is indeed one for a 74-87 truck. Thanks.
