Opinions and Best source for Leaf bushings

Ok what the best replacement bushings for the RE 1492 leaf packs and their Shackles. Discovered last night that all three bushings are worn and the source of the clunking sound was. So what do you guys suggest. Thanks

I was just looking for the same info. I would like to add a greasable bolt also. All the sets that I find are for CJs, TJs, or YJs. I can't find a kit for a XJ. The only difference is I have a Rusty's leaf pack and I can't find out if they use stock size bushings.
