The Disco box
defender and disco 300 tdi gear boxes are the same box,apart from selector shaft yoke and the topThe Disco box is a different size to the defender one but engine is a straight swap as Rich said
to fit the defender top to a disco box you either have to strip box to swap selector shaft and yoke or get one of these from ashcroftsi thought it would be the same and I'd be able to make it fit by swapping a few parts over
Well blow me, I always thought that the input shaft and bellhousing were different between the two. Every day's a school daydefender and disco 300 tdi gear boxes are the same box,apart from selector shaft yoke and the top
