3800 bucks from BTS. Money well spent, and you wont regret it. Problem with BTS is, they are SOOOO good, and SOOO popular, he occasionally has a backorder. Best to call and confirm he can get it in the mail to you.
I've installed a BTS in a friends truck. Its suprisingly easy. 6 bellhousing bolts, crossmember, TC to flywheel nuts, unbolt the drivelines from the transfer case (dont even need to really remove them all the way) and out she comes. Oh, couple of electrical connectors and the shift linkage.
