Yes they fit, though the later turbo's are better.
Its a very easy mod to make fit.
I bet when you turn yours off it sounds like a jet engine winding down
If so dont worry to much, if there is no play in the vains and there are no leaks, though it would be wise to check oil feeds to the turbo for blockages caused by old oil build up, you shouldnt have any problems, some turbo's do make a noise with age but that doesnt mean they are dying.
Mine has made the wind down wine since I bought the 2.8 two years ago, I got in touch with
http://www.dieselbob.co.uk/tips.shtml and was assured it was ok via email.
If you are worried its worth 5 minutes to ask.
Remember though Jim 3k oil changes and 6k oil filter and your turbo will love you, even though it wines
Leave it to wind down before turning off after a run, 30 seconds then switch engine off on a normal 30mph run, and if you have just got off a motorway run or high revs give it at least a minute before turning the key off
