Did they come with 9" rear diffs as standard?

Its just a lot of people refer to the 9" as the RS500 one

Thanks

 

Hi Paul, the road 500's used the same diff as the 3dr, the 9" diff's were fitted to the Grp "A" racer's from about '88 onwards.
There were a couple of variation's of 9" diff also.

as said- diff was just a std 2wd diff (7.5")

 

What were the variations Andy?

 

Hi Dan, the 9" diff's were the Australian "Harrop" made unit and the European "Ford" unit, the CW&P's are different but both are still huge.
The Aussie diff has a spigot bearing to carry some of the loading on the pinion.
Some of the early race car's used a 7.5" diff with a solid mount backplate.
