I have a late model 351W out of a 96 F250. I am trying to get it up on the engine stand but I do not have any bolts that fit the back of the black. So far everything I have touched on that truck and the engine have been held in with metric bolts. So I am assuming the bell housing bolts are no different. I have no way of gauging the threads so does anyone know what size they are? Does anyone have any idea where I can locate that information? The dealership was no help by the way.
