Torque Resto Parts Installation Spade Kit.
 
All the necessary spades to complete a job and get rid of your corroded factory ends.  Comes with 20 spades that are 16-22 gauge to handle most of the wires and 5 of the 14-16 gauge for the heavier ones.  These are fully insulated and heat shrink.  Don't risk bad connections with your new fuse box. 
 
-Install Tip: Sometimes the corrosion on the wiring goes past the connector and begins to corrode the wire itself.  Usually you only need to cut back an inch, but make sure you've got good shiny copper before you slide the spade over and crimp it down.
