i dont get the whole geared diff thing tbh ! i much prefer to run a ball diff rather than a geared diff,i found i was always messing with a geared diff rather than fitting a ball diff and forgeting about it for a few months, geared diff is fine if it just nationals that your doing but running a geared diff week in week out got a tad tiring !
As for the spare parts for the B44.1 , we have most of the parts now and as peetbee says, and is just the chassis, front top deck and front tower that we are waiting for, and at this time i have no delivery schedule, i will keep you all posted as and when
cheers
