Angle drive question

[Delorean17@xxxx]

Hello,
Now that my car is driveable again I want to get the speedometer fixed 
before I put any miles on it(no movement at all right now). I removed the 
lower cable where it meets the angle drive and spun it with my hand and the 
speedometer showed movement so I know there must be something wrong with the 
drive.
I removed the wheel and found that the long square rod that connects the 
plastic cup to the drive gear was missing. I also removed the angle drive 
and it spins freely and looks to be in good shape. Does this mean that my 
angle drive is unrepairable or can I just install a new rod? I dont see it 
in the parts manual. Does anyone have a spare rod they would sell?

Thanks!
David
