727 speedo drive

Hey everybody,got a question,on a 727 is the housing and gear for the speedometer the same as a 904.I used the housing and gear out of my 904 in my 727,seemed to fit but speedo doesn't work.I disconnected cable at trans with trans in gear and running,the gear doesn't turn.If they are different does anyone have one.Any help is appreciated,Thank's
