I think we have had this conversation before
The spindles I found from Western Chassis are 2.5" Since I am going to be putting PB components on maybe the square body 3" drop spindles will fit nicely. Western Chassis/POL are the ones that Nate recommended, plus the steering arm mounts from underneath the arm versus OEM mounts on top which works well with the PB system. I am not sure what the 3" version geometries are?
My wheel/tire combo will also net an additional 1" drop. currently the tires are 31.5" and the new ones will be 29.5".
