Thanks mate I just called Superior Engineering and they advised me that because of the new poly bushes the metal sleeve is not needed in aftermarket leafs. Apparently the Nissan bushes fuse to that sleeve and that's why it's in the standard leafs.

Hi I'm currently installing EFS rear leafs in my d22 and have run into a snag. The EFS leafs don't come with a metal outer sleeve in the eyelets but my old Nissan leafs have these sleeves pressed in from factory. My question is..do I need to remove the metal sleeve from the Nissan leaf eyelet...
