Man, that sounds awesome! Smart doing it the way you are, worst case would be all put together and a no start. I'm glad you're doing this, you're like my road map for completing my 6.4.
I noticed that your engine location allows you to keep your brakes, etc., in the stock location. I couldn't do that with the Magnum Force suspension, I was forced to move the pedal location 3 inches to the left.
