dude, your using english, and its making you appear even more dumb than i thought. why do you think i put the 8.5" in there as an option. there is no stipulations as to what can go in yet. 8.8's are more readily available and cheap. thats why i mentioned it. if this is going to be a makes battle, then yes, i would like the chassis and powertrain of the same manufacturer...the rear end, injectors, etc, i could care less about.
