Two really useful custom things I did to my Maruzen type 96 were to replace the screw holding the mag release catch, and the screws on my zero trigger (if you have one). Go to ace and get flathead or hex screws and hacksaw them to size if necessary. Otherwise, your trigger will be shaking all over and catching at the back and your mag well will be loose and wobbly, and your shots won't chamber half the time because your mag will be hanging out a couple of millimeters.
By the way, any monkey can hacksaw a screw: take a nut and twist it up the screw until it's at the desired length, then place the hacksaw next to it (on the end next to the soon-to-be extra material) and get a groove going there. Keep sawing all the way through, then twist the nut back off to reform the thread on the end.
