I never cared much for the rear plastics. Especially didn't like how my day bags or travel luggage laid with them on so I've been running without them. However I'm going to install a power plate pre filter and because of where it sits it would be wide open on the sides for water splash, branches, etc to get to it very easily. So taking my queue from some others I've fabbed up some side plates that sit flush with the frame. All I had on hand to make them with was some clear plastic. It wont stay clear long but I'm kind of digging it in clear. Might leave it that way for a minute.
