I know the title sounds good but today whilst out on the boat one of the kids bumped the wall and complained of being spiked ( nearly at head height) with some investigation I found the trim nearly holed, turns out the screw from the shower curtain retaining clip is way longer than required, with a screw driver and a pair of pliers I have shortened the screw and all is well, have taken pics it may be worth checking you own, mine is the 2002, 3500 SCR
hard to see but it nearly pushed all the way through
the offending pop clip in the shower
the amount I cut off the screw to reduce the risk
