Here is a good shot. The drag link looks aftermarket and the tie-rod ends are def. larger than the factory stablilizer bar:

I measured a 3" drop pitman arm:

Factory stabilizer arm tie-rod shot (this is what i am not fimilliar with rebuilding)

Again, i dont know much history on this truck. What i do know is it does have extended brake lines, spring over axle perches (but springs are below the axles), missing stabailizer bar, 1" rear end drive shaft spacer, 8" shackles front/rear. I get the feeling this guy used to sit much higher and maybe somone stole/swapped parts before the sold it. It currently has 31" TSL's
