You've removed the center clip and the reluctor and lifted up the top flat plate slightly so the nub on the end of the vac can arm comes out of its hole in the flat plate and the 2 screws for the vac can & removed the can. Take out the 2 addition'l screws on the side of the housing & carefully without tilting it severely lift both of the flat plates up & out evenly together. Once out flip the assy over & remove the triangle clip so you can seperate the 2 flat plates. Unless the new pickup coil comes with the top flat plate as an assy (never bought one) you'll need to drill out the rivet so you can R&R it. I make a magic marker mark on the top plate and the housing so I can quickly orient their clocking when going back together. You can figure it out but it saves time & is easy to do
