Your truck originally should have a 208 transfer case.Go to a company I belive the correct name is Trans Dapt .They have conversions for pretty much any thing .I'm in the process of a 4 spd to 700R4 and I want to use the 208 transfer.I belive all you change is the output of the trans to adapt to the transfer.Keep us posted and sorry I dont have a link to the site .
