Stock tie-rod and drag link, which should fit the Duff brakes I do believe. But a heavier duty version would be called for normally, just for the size of the tires you'd be running with that much lift.
Can't see the upper end of the trackbar to see if it's adjustable, but it also looks stock from here. The trackbar bracket and pitman arm are of the dropped type, which is needed for taller lifts, but they are also designed around a 3" lift or so, which means that they are not enough for a 5" suspension lift on their own. They help, but usually Broncos need more correction to keep their owners happy on the street.
No way to tell from the pics which C-bushings are in place, but you can see that the pinion is pointed in a notably more downward angle than normal, so there was probably quite a bit of caster added. As mentioned, likely some built into the radius arms (hopefully) then the added offset of the C-bushings.
I've seen those radius arms before, but don't remember the details. I want to say that one of the companies like Tough Country (not Rough Country) had something like that for awhile.
Five inch lifts make this relationship between steering angles, caster angles and pinion angles very hard to correct. You can't just keep tilting the axle back to regain caster, because the driveshaft u-joint will eventually bind. The more the lift, the more likely that result. The more the offset in addition to that lift, the more likely that result.
Best thing to do right now would be to have the alignment checked to see what the caster is reading now. Might help make the decision to rely only on the bushings and arms, or go with the old "cut-n-twist" method on the front axle.
Any plans to go lower in the lift department? If not there are some other things that might come in handy with that much lift. But it all depends on how it drives now.
Good luck.
