I just took mine completely apart (the whole t-top assembly). The center piece in rivited to the falt piece that the weather strip sits in (well, it's supposed to be, mine were rusted through...) The only way to get it out is to carefully drill the rivets out...it's double sided so reattaching it might be a problem.
MY SUGGESTION: Fix it attached to the car. Mask off the car and shoot it with some trim black. If I wasn't painting my car that is exacly what I would do. Taking it all apart is a major MAJOR bitch.
