I just got done reading your whole build thread. Excellent looking truck. Very similar to what I've got in mind, but I don't have much disposable income right now. I'm looking to do an SM465/NP205 swap onto my Banks 6.2 for now. I've already got the trans/t-case, just trying to scrounge up the hydro bellhousing, pedals, cylinders, etc.
Very cool thread! Who'd you get to make the crossmember for you? What'd it cost you compared to the Avalanche one?
