Hey Everyone
After looking around for a good, inexpensive method of changing the focusing screen on my Mark III, I decided to try and fit the 5D Mark II eg-s focusing screen into the Mark III. It works!
I was able to install the Eg-s Focusing Screen for the 5D Mark II, into the MK III without any problems or modifications to the screen Works really well for me! The Eg-s screen is ony $35 too!
I made a video showing the installation process:
