i jacked up the rear end of the Z ('78 280z) and noticed that there's some, well actually a lot of play in the diff carrier bushing. i know the 240sx's have a full subframe that can be stiffened with collars/spacers. i'm not really sure if the same kind of upgrade is available for the s30. also, i'm not quite sure if the bushings are worn, or supposed to have that much play.
i searched for "240z/280z subframe collars/bushings" but havent found anything yet.
any help and ideas would be greatly appreciated!
thanks in advance!
