how were the heads mounted on the wrestler and ufc fighter 3.75 build n brawl figures ?
how much work is required for a swap between one of those and Gi Joe figure ?

bnb were just a ball peg that went into to neck. boil and pop (sometimes the whole peg pops out)

usually a dremel with a ball burr to open the head hole up is all it takes to fit on a joe neckball. if you dremel out too much a piece of heatshrink tubing cut and inserted in the head is one fix, others use (ewe) hot glue...
