Haha! I just PM’d you with the answer on how to remove the chrome caps, I didn’t see this post earlier, so I will just add it here.
The chrome covers are simply a slip on fit. They get stuck over time, grab firmly and twist and pull straight up, maybe shoot a little WD-40 in there if necessary. The underlying rubber dust cap has a lip that snaps into a groove around the top of the fork lower legs, when they are in place and you slide the chrome cover over them, it sort of locks everything in place.
