8.8 swap

This site has a lot of good information The Ford Explorer 8.8-Inch Axle Swap

I did mine for a 67 fastback.

67 Fastback getting 8.8 rear
in this article you posted they say that people have put a 8.8 with discs in and not had to change there master cylinder? Can any one confirm they did this or that it works. Also will having drums up front and disc in the rear be an issue?
