pretty sure they are. BTW, never rush ship something from PDM. They're in Canada and it costs big $$$.

Energy Susp has some, too. Check places that distribute them. What's the rush? If you need to slap stuff together, just drill a 3/8" hole in the side and pump that bastard full of 3M Window Weld. You'll have a polyurethane filled bushing and it'll only cost you $12.
