Hello once again. While attempting to remove a stripped screw from Galvatron's Particle Cannon, I managed to destroy the swivel where the rear and landing gear rotate. What I have salvaged are the gun barrel, rear box thing, landing claw, and the original piece which plugged into the bicep. I also possess a 5mm port and peg. My hope is to unite the port to the barrel and the peg to the flat face of the box object. this will allow for the Particle Cannon to be a bit less massive and possibly still fit in Galvatron's alternate mode (not the jet, for I care not for the jet). My intention is also to fit the redone gun onto the forearm like the cartoon (somehow). The catch is the fact that I am a little hesitant to do anything yet, as I am new to customs and unsure of the optimal path to an acceptable firearm for the figure in question. Please provide input regarding this predicament.
