Spotbiltxo...Classic Parts. (www.classicparts.com) Seemed to be good quality and tightened the springs...no more rocking side to side. I had custom 3" lowering blocks made. Before I install them I want to be sure that they're properly located. What I didn't know before replacing the bushings was how much if any fore and aft movement existed from the worn out bushings. There wasn't any. I'm planning on installing a small block so it's a good time to go through all of the driveline.
FYI...the original shackle bushings were not worn through, only egg-shaped. The front bushings were half gone.
The all thread press worked slick. If you want I can explain the components.
