For your convenience, this rubber gasket will act as a barrier between Early Defender & Series rear tub to cross member (with 5 tabs). This barrier will help prevent the two dissimilar metals touching and causing an electrostatic reaction. The gaskets are 1mm thick single sided adhesive, so you can either stick the gasket to the chassis using the adhesive or leave the tape on if fitting in situ.
1 kit will do both sides.
