What I'm after is some idea which differentials were fitted in the 2.0 DOHC Sierras. Ratios or diff codes would be fine. I'm looking for a diff, and just need to know if they are all the same (so I get the first one I find) or did Ford put different ones in different versions of the car.

Cheers

Mine was J reg 2.0 GLX, and had a 3.62 diff ratio

Jolson,

There's quite a few variants- I think 5 atleast. A list has been posted several times so a search should turn it up.

HTH,

1990 2.0 DOHC 3.62 ratio.

To answer my own question.... I got a donor Sierra on Tuesday. It's an H-Reg 2.0 DOHC GLX. The diff code is D, which should make it 3.92.

Cheers

John
