from what i understand the inner joint is just that, just the metal bit that goes into the diff/indermetiadte shaft speedo housing
if you want the rest you've got to order the whole shaft
i know that you can remove the bit with the 3 balls on it and retro fit it as i've just send that lot to someone off of here
how bad is the damage to the joint that you are missing though as i'm sure mike rainbird's emporium of fancy ford bits has them for sale
