Once again, LOTS of info on this site on this subject. Run a search for 700r4 swap.

Here's a few links to start with.

Basically you need this installed in the 700r4 and then move the engine forward 2 inches to the "2wd engine location". There are other methods to achieving this swap, but the adapter shaft I linked to is probably the most popular and well documented here on the internet.
