Are yours missing? If you have them you can rebuild them if there is not any bad pitting in them. Rockauto has rebuild rubber kits for next to nothing for price if yours are rebuildable. Worst case, you can send them to White Post to be rebuilt. They will sleeve them to make sure you have a true bore but they are not cheap
Rare Parts makes the idler assembly now? That’s great to know, Jim. Thanks. I’ve been limping along with the crappy Chinesium idler repair kits that Kanter sells. They seem to go bad after a few years.
