Yes,
Ashcroft built the gear box as I had bigger clutch packs and pump fitted and valved for a diesel I did the rest.
It wasn't too bad just take your time I got all parts for the job from Ashcrofts as they do a nice kit, had to have rear prop altered made 15mm shorter and fitted a front from the discovery 2 auto which is 15mm longer if you leave the gear box with the std pump you can use your prop shafts on the zf22, I think that the 24e is 15mm longer than the std box due to pump.
Give Dave at Ashcrofts a call, he will help you even if you don't buy from him.
It was worth the trouble and cost, it is really nice to drive on and off road.
