Radius arm bushings
Replacing radius arm bushings on a 79 f150 4x4. Got the poly bushing kit. Do I need that nylon spacer on the rear radius arm bushings, or am I good just using the cupped washers? Original spacers nowhere to be found.

thanks, that’s what the LMC diagram suggests too. The front and rear bushings look the same. In other model years, they were a bit different with a nylon spacer between the body mount and the rear bushing. I’ll take a look today to see if there’s a large amount of play between the bushings that should be taken up by a spacer

Is the spacer like a really thick flat washer to take up space lengthwise ... or is it ... like a tube preventing contact steel radius arm long rear shaft to steel frame bracket?
Did you use straight poly replacement C bushings, or did you opt for some with added degrees of caster added.

I’ll let you know. I’m still months away from being road worthy. Pics don’t show it, but currently no motor on the rig. Have a rebuilt 400 sitting on a stand right now waiting to be installed. I figured it’d be easier working on the front suspension while the motor was out. The C bushings were fun to install, especially when you snap off a spring cup bolt that goes into the radius arm. Had to drill out the bolt and retap the hole.

Yeah, getting the first coil spring back in is easy. But once it's installed, the other side is under tension, and it's difficult to line up the two bolts in the cup. I experienced that when I installed new C bushings. A couple of years later, I decided to change coil springs. I dreaded fighting those spring cup bolts. I ended up getting a set of aftermarket spring cups from Duff. Those things made the swap a total breeze!
