Hey, anyone know the diff ratios for EA/EAII? I think the 4-spd auto was 2.77:1 and the 3.2L engine had a manual 3.00:1, but that's all I know.

They were a bit all over the place, but this is what I've found:

GL/S/F'mont 3 spd 2.77:1
GL/S/F'mont 4 spd 3.08:1
GL/S/F'mont 5 spd 2.92:1
F'mont Ghia 3 spd 2.77:1 LSD
F'mont Ghia 4 spd 3.23:1 LSD

Thanx dude, that'll help. Thought m car was 2,77, but according to your info my EAII Fairmont 4-spd must've been 3.08:1. Much appreciaited.

If you get under the car and have a look it should say what it is on a tag on the rear of the diff.

More or less correct, however

GL/S/F'mont 4 spd 3.08:1 isnt 100% correct

3.08:1 was used in all CFI cars
3.23:1 was used in MPFI cars wether GL/S/Fairmont/Ghia
