Here is the thing... You probably wont need a longer shaft, but it is a slip yolk design and will be at the max outward travel, where as stock it is centered up, or just a little farther in. The kit will use rear blocks, which have the built in degree shims that help angle and driveline length.

You gas lines should be OK, unless your talking about a body lift? The exhaust on that truck has to be modified to clear the front driveshaft also.

Wheels and tires are another big factor! 35x12.50x15 I assume is what the kit is recomended for, Larger tires without a body lift is not possible without cutting some metal.

You may also want to get the matching skid plates for the front to cover up the hole where the front drops down.

And last is a new set of gears. If you run 35's I recomend 4.56 ratio! That is what is in mine and It has all the power like it was stock. I didnt have to change the speedo since I used the gears to offset the tires.
