As far as the manual goes they have 4.625:1, 5.143:1, 045.833:1 for the Mk1 Transits.
If you are interested in a highway diff I have one for sale - I think the ratio was 3.76:1 but I will check the number of teeth tomorrow to be sure.
This is for a twin wheel Transit but after I bought it I realised that my V4 just wouldn't have enough grunt on big hills with this ratio diff.
It uses Transit axles and hubs, but has a Falcon (X series I think) diff centre - it was professionally done and I think the remains of the maker's details are still on it.
