i managed to drop out the box change the clutch and swap the box for a good second hand one in a day. did it on the drive with a engine crane through the door, and some help from a mate. I did it as id been charged £316 for changing a clutch for 2 years befor, id go for a day doing it my self again if mine gose on my new truck. And it cost about £90 oem cluch, both parts, and do the fork while your in there.
