    About 20mm wider than 86.

    Spring seats are way too small to use 86 springs on.

    Arm mounts are off by about 10mm but is still doable if your keen.

    Ratios are usually around 4.1 I think...

    ra60 diff requires:
    ra60 tailshaft
    new springs or seats
    some kind of bushes for the diff mounts or drill out the crush tubes in the trailing arm bushes.

    unsure about cables.
    trailing arms fit fine with abit of creative jacking and hammer work.
    dont drill out your flange like me, you will screw up your motor/gearbox and diff through vibrations.
    ratio is 3.9 im pretty sure. not sure if its auto or manual.
    zenki lsd's fit
    10mm extra track each side
    ae86 panhard bolts up but i think you need adj.
    ra40 diffs need swaybar mounts welded on ra60 do not.
    86 springs can work but look like they will fall out very often.

    thats all i know.
