Hey, if i was to say the km's i would be telling lies, i would say not a great deal but i am no gearbox expert!
as for the imput i would now say it has a os one as its didnt look like standard nissan gear on the end as you can see in the photo, the left top gear connected to the imput
i was going to actually ask you Paul, where to take it. but now i know!
what do they usually charge to overhaul one of these if everything checks out ok?
