I don't really know if it's a early one or a late one, I had another gearbox under bench that I thought was a xr3i and it looks different but the part number is the same so that must be one of these ib5 also. Fingers crossed will be ok. The updated luk clutch will prob be first to go but I hate paddle clutches
