A wheelin' buddy up in Washington had a FJ40 with a 5.0 Mustang GT, T-18 mated to a Toyota Pickup t-case. He beat on that thing with reckless abandonment, and the only problem was one day he was pulling wheelies out on the street, and after a couple of good wheelies, he twisted the output shaft off the t-case. I am not sure, but I think he just replaced the shaft and ran it. I was impressed.
