Cost of a job like this depends entirely on how you do it, who you know and what you can do yourself.

If you scrounge for good deals, do lots yourself, have mates in the trade and are happy to live with 5stud then you could probably shoe-horn one in for $1000 or so.

But if you just go to a shop with a Hilux housing and ask them to make it fit, change to 4 stud and build an LSD to go in it then it could easily be up round $3000.

So it really just depends how long your piece of string is.
