Hi all,

I have got hold of a diff from a granada 2.0 auto, it is the same casing as the one i have fitted fom a 4x4 sierra.
Without me taking the back plate off, does anyone have an idea what ratio it might be??

Cheers, Rich.

To answer my own question......

Found this on a ford forum - codes found on the tag on the diff cover.

Push in type shafts

KC 3.14 7"
LC 3.38 7"
MC 3.62 7"
JD 3.92 7"
DA 3.91 7.5"

Bolt on shafts

BA 3.14 7"
GB 3.14 7.5"
DAA 3.14 7.5" LSD
FA 3.36 7.5"
AAA 3.36 7.5" LSD
AC 3.38 7"
CAA 3.38 7" LSD
BC 3.62 7"
BAA 3.62 7" LSD
AAA 3.64 7.5" COSWORTH (this has the same number as the 3.36 7.5" LSD BUT is ID'ed by 108mm drive flanges)
ADA 3.64 7.5" GRANADA COSWORTH
DC 3.92 7"
AA 3.92 7" LSD
GA 3.91 7.5"
ABA 3.91 7.5" LSD


As it happens, i have got hold of a 'BC' so no speed callibration needed
