just pick up a set of punches should be less than $10 or if you choose just get a small and medium
brass punches would be preferable but steel ones will work if you can't find the brass ones
other than that a screw driver, needle nose pliers, Hammer, once again brass preferably, possibly long allen wrench and for the grip, and some tape
another quick trick for that pesky front pivot pin detent and spring is find a allen wrench that will fit in the hole that the pivot pin rides and stick it in from the left side drop in your spring and then your detent while holding it down with your finger push the allen all the way over it, then take your pivot pin and line it up with the allen wrench and push it in to place an voila your pivot pin is installed. works like a charm but i would still put a 1 gallon plastic baggie over it just in case you end up lanching the spring and detent,
