i dont know, but the bars are the same. i have a feeling those part numbers might be backwards.
I buy them at the JY.. $10 each.
Heck...even sways are $10.
FWIW that piece probably isn't stripped on teh rear. There's a nut behind the bar that you have to look closly to see. Put a 15mm? I think it is between the bar and the link. That'll hold the bolt and the nut will come off.
