Okay, idea just crossed my mind, keep the white top and bottom, extend that burgundy (or what ever it is) up the whole side of the truck, pull the rear most side windows and fill the holes with sheet medal to make a 'panel' look. Bags. Stock trim and bumpers and handles and everything else to keep it clean... like the lowered one below, but filled windows like the camo one...

You've gotta be the only one on here who's happy to have found a pinion leak.
I assume the axle linkage is for the late-model adjustable rear brakes?
That's the load sensitive proportioning valve , it's suppose to give you more rear brake bias under load . But they usually rust up solid and don't work.
