If my memory serves me right...(it's a hit a miss sometimes), my 79 bronco had a 390 motor mount on one side and a 302 motor mount on the other side. My Bronco originally had a 351M until is was replaced with the 460. I later upgraded to the L & L's, but I have since heard that the M series and BBF's are the same motor mounts. I have not compared the two side by side though.
