Hi All,

Well I've just purchased a MY95 STI RA box with the drive ratio of 3.9 to fit in my STI 555.

What rear diff would I need to match this gearbox and what models of impreza could I take one from to fit mine ?

The gearbox I have is TY752VB3EA.

you need to check to see what ratio you currently have (will be either 3.9 or 4.11) and change as needed

Cheers Alyn, I've currently got a 4.1 ratio diff.

Could I take a diff from the later models like bugeye's and so on with 6 speeds and take the rear diff from one of those models as I believe they are 3.9 diffs.
