Have trouble pegging in Optimus Prime's chest peices? Are they ready to break? Then follow this easy procedure to make it a snap to get those pieces in! Ok first, all you need is an exacto-knife, or any sharp knife that is small enough. 1) Look at the vertical groove where you peg the chest pieces into. 2)See those small horizontal lines on either side of his speaker chest? You want to cut a small hole into those lines, starting from the bottom of that small detailed area up to about three of those horizontal lines. Cut just about a millimeter deep. 3) The pegs should now slide right into that hole you made and you will now no longer have to break those pegs to get this to work! I hope this procedure helps you guys! I have attached a pic for a better visual description. I circled the holes I made.
