    I want to restore a gear box for an Autin 3,000 bt7
    1960
    do you have a cost for a complete restore?
    Thanks

  4. markjones says:

    Hi George..It is difficult to say without a full teardown, but it will take 12-14 bench hours labor ($1300-1400) plus parts, usually $400-600 for bearings, seals, syncros, gaskets assuming no major internal damage. Cheers..

  5. George Robles says:

    thanks for the reply, do you have complete restore gear box.

  6. markjones says:

    Nothing rebuilt in stock at this time. I generally rebuild to order. Cheers, Mark

    cost to rebuild a 3000 overdrive?

  9. Mark says:

    Healey rebuilds are typically around $900 for the gearbox and $500 for the OD unit. Parts extra, but usually $250-300 on units with no major internal damage of expensive parts.
