I ended up removing the original face on the left side of my fence and replacing it with a taller piece of beech for the purpose of attaching anti-kickback rollers (a la the ones David Marks uses on Wood Works). Anyway, if you want to replace your fence face you'll need to cut through the laminate in nine different places to remove the hex-head sheet metal screws that are holding it on. Biesemeyer laminates the
1/2" ply after it's attached to the tube. I used a rare-earth magnet to find the screw heads by sliding it along and letting it self-center as much as possible. I then drew around it with a pencil and used a Dremel plunge router to pierce the laminate at the center of that circle. That allowed me to find the head of the screw and then carefully remove only enough laminate to get a hex driver on the screw.
Now that I have my new face attached I have a flatter face than what was originally installed (not that it was bad) and I can shim it from above or below to square to the table (which wasn't necessary. The 9 screw heads remain exposed on my fence but are not a problem. And I did have to move the little plastic hairline guide on the right side of the T so that I could zero-out my new fence but that just required drilling and tapping a couple of new holes.
Sorry if that's too much info... :)
