I will have pictures up in the next couple of days, but you don't have to cut the dash at all, just replace the center dash piece, remove some connectors for the wiring from the stock am/fm unit and cassette/eq unit from the amp, 2 bolts and the amp drops out. 2x clips to remove the bottom of the center dash and it slides out. This is what you need and you can find other colors depending on your truck:

This is the kit I used and it was not too bad. Hardest part for the entire install was mounting Amps, Replacing rear speakers in the rear pillar on an extended cab, and running the power wire from the battery to the distribution block for a two amp install. Well worth it though as to get some nice audio in the truck.
HTH,
