That's what I am doing, but it requires that you change a lot of other stuff as well.
razrwild.... That is a good looking truck for the price. As the others have said...I would not be overly concerned about the D35 for right now. If you have access to the 8.8 for a good price ($200 or less) then get it, but don't go crazy trying to find one and over pay.
You don't HAVE to change the other stuff, but it cleans things up nicely if you do! (I did mine already)
