Just an FYI. If anyone out there (maybe I'm the only one) has ever broke the knobs off the interior back door pc (4 red plastic screws) that holds the cover on, an easy fix is to get a wood dowel the same dia as the hole thru the knob. I snapped 2 of mine where the head meets the thread. I ran the dowel (with glued) all the way thru the threads and as far as I could into the head. Way stronger now.
