I haven't done that one yet. Does it just have some tabs that are kind've spring loaded maybe? Sort of the type of thing where you squeeze the shield from the sides to pop it off?

Let us know what you figure out.

I finally noticed the screws holding on the shield. Took about 2 minutes to do the mod once the shield was off. Sheesh...
