The only thing I can suggest is to call them directly. The customer service guy put me on a waiting list for a new idler arm assembly (not just bushings)--You install the new one and ship the old one back to them. Labels are included in the box. They have always been really good about sending things out, though our schedules don't completely mesh at times. Call them.
