Congrats on the swap. I'll admit I cuss my ZF6 sometimes, but both trucks I've built were 6 speeds. I spent an extra 3 months finding the truck I wanted both times just to stay away from the auto. Hard to come by a 4x4 reg cab 6 speed 7.3, really hard to find them in good shape. You will love the manual, just remember sitting in traffic your left leg hates you.
