thanks for your opinion I will probably buy new as I normally do but having had the luck I had with the engine I bought off ebay ( a real peach compared to the lump that did not make it home on the day of purchase ) less than 100 miles and bang whoosh a cloud of oil and steam less than a mile from the driveway I might think new cv old transfer box and old zf should I go the whole way and for the extra £200 and renew transfer box then we have a reworked transfer ox old engine old diffs old zf auto and so i go on and before you know it you spend 3 days under the vehicle and £2300 and the only thing actually broken is the vc but hay ho who knows until it's fitted weather or not it is any good.
