Front end rebuild on the menu in P15-D24 Forum Posted January 7, 2010 · Report reply Darin, I may have been barking up the wrong tree. I was thinking the P15 might be the same as my P24. here is a photo of the two sway bar mounts that came off my broken P24 sway bar. There are also two more rubber mounts at the extreme ends of the bar. On these mounts, the rubber pieces seem to be captured pretty tightly in the mount which is spot welded together. Sorry to get you off the track. The P15 setup might be way different. The insulator pad, I can't say, since I'm still running with a badly deteriorated one. My guess is that the main purpose is to dampen road vibrations so they don't transmit to the frame.
