The old pieces are easy to take off but you do have to pull the door panels off to completely remove them from the door panel.
The trim pieces have clips and a few screws from behind holding them in.
I haven't done the console pieces yet - I am still trying to decide if I like the ones i already did. From the looks of it you would have to tear apart the console to get them completely out.
I own a cnc mill and am thinking about making some billet inserts if i ever get time.
