    A520 ring and pinion

    Hey Guys,
    So I'm rebuilding my A 520 transmission out of my 89 turbo caravan. The trans itself is an 87, which makes it the early style 520, with the 350 final drive ring and pinion.
    The bearing seized and destroyed the end of the shaft. I need a good used one with no pitting on the shaft where the bearing races rest.

    If you have the 89 and up 520 setup, that can be made to work for me.
    Thanks,
    Lee

    Haven't found it yet. Might have a520 trans complete somewhere. Will look again some more in morning when not as hot in building.
