while this is the offical way to replace an inverter, those of us at the repair depot quickly learned a much faster why that only involves removing the display bezel and clutch cover.
remove display bezel like normal.
remove the 3 screwa from the clutch cover.
pry lose the clutch cover while the lid is open and then some more when it is closed to get it to pop off.
replace inverter and then carefully replace the clutch cover in the reverse of before.
you may need to clip off the top parts of the tabs inside the clutch cover to get it to replace easier, these serve no purpose and can be safely snipped if needed
we had a few thousand macbooks on hold because we had ran out of stock on the inverters that we were forced to come up with this method to get them all repaired in 1 day when the shippment of inverters finally came in after 2 months of being out of stock. this turned a 30-45 minute fix(including our documentation) into a 5-10 minute fix
