The CV front shafts are awesome if your truck has a big lift on it and you plan on going playing in it because it lets you have that much more articulation in the shaft itself. I am running these front and rear on my CJ and front on the Ranger.
The 1350 T-Cases are super rare just as said before, and best found in junkyards since your looking for cheap. Best if you find either a Pick a Part or something of that matter just because the drivetrain components such as t-cases and trannies are left in the trucks until someone pulls them out to take, unlike other yards that pull the engine, tranny, and t-case when the vehicle arrives. They are usually in the bronco II's, but sometimes you can score one out of a ranger too. If money is more important than time, just keep searching the yards and craigslist, one will show up. Junkyards are how i built my entire underneath, including the 6" skyjacker kit
