You'll need the usual assortment of tools, plus a thread-locking compound; in this case, make sure you have a tube of Loctite Blue.

Don't put all the old hardware away just yet, because some rearsets reuse stock components. (For example, on the FZ1 installation, the forward Heim joint on the shift rod is retained.) Nonetheless, when you finish the job, you'll want to store and label all the original bits.
