    right guys

    Give me a list of what’s required

    I’ve just removed my 2.9 ratio large case diff from my 323 coupe and I had panned to put the 3.38 in its place

    Noticed shafts are smaller and shorter, I looked at swapping the cups but they are longer and won’t lock in as the ring grove is in a different place

    Can the swap be done or where do I get a large case 3.38

    2.93 diff is medium case , large case in m3 evo stuff , you needs shafts and rear half of prop to swap to small case

    I have a compact that I’m breaking but looks like none of the parts are swappable

    Where are you located then
