Hey guys. Having a little trouble matching some spring bushings. This is for my 75 fj40. It has skyjacker springs and HFS shackles. The shackle to frame bushings are the normal ones that ccot sells. The lower bushings however have a thick rim on them. About twice what the upper bushings are. I’m having a hard time finding these, I’m sure I’m missing something obvious here. Anyone happen to have the a part number on these? Battery died on the harbor freight measuring fork sorry.
