just found out my gearbox is ****ed, i been advised to send it off to somewhere called stevensons in preston and let him rebuild it, think i may have been there before, not to sure, so, i'd like to know what other options i have in this situation, other gearboxes that will fit, and take more punishment, and generally make the car perform better/quicker, or do i just get the williams one rebuilt and wait for it to go bang again

any idea how much a rebuilt box would cost?

cheers
