This seems to be the most likely messed up area. #8 is a strip of 2 mm thick foam approximately 7 mm wide and 7 cm long
adhered over rivets and the latch plate. I installed three short pieces of 2 x 2 mm foam strips at #9, #10 & #11 to fill in
the gaps; #9 is about 16 mm long, #10 is about 22 mm, and #11 is about 18 mm long. The back pictured is NOT the one I worked
on. Please note I have had my SQ-A only a short time and am no way any sort of expert.
