Thanks for asking this question. I have a 57 3 speed overdrive that I have been thinking of putting in my 53 wagon. I like John's suggestion of using the tailshaft bolts on the main case. Also the idea of using the rear of the engine. I think if you have the crossmember that bolts to the bell housing that could be used/modified if needed. If I go this way I can keep the original tranny cross member that has the emergency brake attached, and keep the emergency brake with very little modification. I have a 55 3 speed overdrive and the 57 both don't have a mount built into the tranny. I guess, just the way they made them. I don't know if this helps but good luck and thanks
