There is a lot of down time, especially since I am taking my time and am just trying do it right the first time. It's definitaly not my daily driver. There are little things that come up, but having a complete donor truck made the swap a lot easier. I had to buy a W56 transmission to go with my gear driven duals but I used the bell housing out of the 96 and put it on the W56. Overall the swap is going a lot easier then I expected, it really does kind of install itself. I have yet to do the wiring, saving that for last, I anticipate that to be the hardest part.
