Also, follow the article's suggestion to go out and buy some replacement phillips screws before you take anything apart. Even if you do everything correct, you will most likely trash the heads on these guys, making them useless to reinstall. That lockring can also be tapped left and right as Tone mentioned -this makes it a *little* easier to remove those 3 screws. Next time I do this, the replacements will have slotted heads -this should make it that much easier to tap out the in the future.

As for the hubnut, seriously, go buy the Ford part and file down the "nubs". A hacksaw and a file will do it easily.
