I just installed some from Wild Steed Works on my 05 Chopper. Very easy and oh what a difference. Just loosened and removed the bolts and cup washers. Gently let the bars hang, removed the old rubber and metal bushings (the rubber was deformed and in serious need of replacement), pushed in the new poly ones and bushings, topped off with the included metal caps and bolted back on (added some blue thread locker).
Noticed the difference right away. I should have replaced them earlier.
