I've replaced dozens of the LCD's and I don't recommend this method.
The guide itself is poorly written with it's missing instructions (what mod to the clutch cover, how do you get the clutch back on), it's out of order, step 6 shows the clutch cover off and step 7 is taking the clutch cover screws out.
In using this method the Airport wires can become pinched and damaged at the other end. The Display Data cable takes abuse when you try to force the clutch cover back on. I know this because I tried it to see if it was actually possible to avoid the steps in the proper method. The casing on my gray Airport wire was damaged and the DD cable was interfering with every attempt to replace the clutch cover. I ended up stopping at that point, disassembled it properly and replaced the left lcd frame and Airport wires to avoid and further issues.
It only takes 30 min to do it the right way, save yourself the hassle and do it that way.
