I just installed the RSI on my 13 was not hard I used a hand held power shot stapler it is manual uses T50 staples I used 3/8 long, not hard to do stretch it nice and tight and fold over the edges on corners or where needed to keep it tight, just look at the existing cover and do the same the you will have more excess coverage on the RSI cover so I just stapled the extra further up the pan, I don't have the sled here right now getting long rod and PAR head or I would send a picture.
