Old Drop Axle Mystery, Made From Steer Axle?

Well I picked up a good heavy spec's truck to pull a lowboy with, I've pretty well got the old girl figured out, but my drop axle has got me sure stumped. I'd like to get the brackets, Pederson I believe, so I can make my fenders raise and lower with my drop axle, but I don't know what I've got for a drop axle, I can't find a tag to read.

It does have spots on each side's knuckle for a drag link arm to go in, now that is just open with nothing in it, This could be a good spot for me to make my own brackets, but I'd really rather buy something already made so I can just bolt on. This having these on both sides, and the construction of the axle part of the drop axle, it really really really looks like a old 18k or 20k steering axle, that was put onto a air up / air down suspension.

Truck is a 98 KW, couldn't tell you if it came from the factory this way or not. I'm not sure how they were building drop axle's in the late 90's. My fleet at that time consisted of Tonka trucks, not real ones. I will get some pictures to upload tomorrow for a visual, not just a text explanation.

 

Here's some pictures of the sprinkle / knuckle. Sorry it's been a few days and thanks again to anyone who has some ideas.

 

frame mounted ones are what's on it. Would like to go with axle mounted fenders
