I concur with this statement, wholly reccommend Andy & Stuart at LandroversUK, successful transplant on my knackered 110 2.5TD with a spanking 200Tdi from a Disco, no problems when little things were noticed after the work was carried out, took straight back and sorted there and then. no hanging around.
Again on the plus side you get new clutch, timing belt, new hoses, bespoke downpipe, remarkable transformation on my 110
