One easy way to delete the belt driven vacuum pump and still keep your vac system is install an electric vacuum pump with a small vacuum tank up under the truck along the frame rail some where.
There is a lot of room under these trucks and even more so if you can let stuff hang down a little, but I think you can only do that as long as you don't have to worry about deep snow or off road mud pits tearing stuff out from under your truck.
