Forgive me if this is common knowledge, but I found this mystery weight/emergency hockey puck bolted to the top of the engine cradle just ahead of the pass. side motor mount when I was doing my 3400 swap into my 86 2m4. It's solid steel, about 4" in diameter and was just bolted there with that single bolt doing, apparently, nothing useful so I left it off.
