    Default Diffs?

    I have a 1976 HiAce Commuter with a 12R motor and 4 speed box. As it was a bus it seems to have a low speed diff in it. Someone told me that certain Ford falcon diff centres would drop straight in and so increase the top end speed or more importantly decrease the revs required for highway speeds.
    My question is, does anybody here know what model Falcons are suitable? I have to do it as cheaply as possible.
    Thanks

    Don't think it will fit - believe the HiAce was a E series diff.
    Check the build plate for TransAxle - it will say something like E292 etc - we can thenpoint you to a lower diff ratio from another toyota - unless i'm massively wrong...
    Here's a website with some diff info on Toyota's: http://www.geocities.com/MotorCity/P...rivetrain.html

    Hiace diff will be G series, it's the Liteace which has E or F series diffs.

    No chance a Ford diff will fit in a Toyota (well not without custom fab work), but there are a huge range of G series ratios available.
