I found a leader class optimus prime at a flea market. It is missing the two front tabs that would go on the top in alt mode and it would be the shoulder pieces in robot mode. These are the blue pieces that snap on a ball joint. The other piece that was missing was one of the vents that cover up where his fist is on the back of the rig. If any out there have these pieces could you let me know what you want for them? Thanks.
