Looking at part number 13 on the diagram.
I have the Touring Sedan 22mm rear sway bar, which is a bit of an oddball. To replace #13, dealer quoted me two parts up here:
Link Assembly part # 25602320
Insulator for 22mm sway bar # 25558129
Problem is, for both sides they wanted $78.09. Figure I can do better, which is whey I am asking about this. The link assembly is easy to find. GM PD has them. Nothing comes up when I enter the insulator for it tho. That is the part I am trying to find.
Probably a good idea to order the end links from Energy at the same time. Anyone know a part number for the rear bar?
