Alot of work will need to be done. But your first step is to search this forum!!! This has been discussed many a time!

It's a fair amount of work but it can be done. There are a lot of additional parts that are needed such as the pedal assembly, shifter assembly, master cylinder, some other stuff too. The write up is for an AWD but except for the transfer case it's pretty similar. I don't know what a shop would charge but I would say if you can do it yourself.

A shop would screw you like a $12 hooker in Vegas. It would cost a shit load of money. Whats labor, like $60 an hour? Yeah, it would cost around $10 million. Do it yourself.
